The practice dashboard consists of two pages.

  • A page analyzing performance goals
  • A page analyzing practice performance

The Goals analysis page provides context to the Practice analysis page. There is a key (shown below) on the page that explains every metric.

goals_dashboard_key

The best way to understand it is to explain a few examples.

 

goals_dashboard_example

The third bowler on this list has a 171.5 median along with a GOAL headpin % of 91.39%, a GOAL single pin spare % of 69.77% and a goal 30 point average of 0.93. If anyone is interested in how these goals are determined, ask Coach William.

Notice the colored columns for this bowler indicate that a focus on spare conversions is a premium when practicing. Also, some consideration needs to be given to the 30 point average which would require focusing on “transition” and other topics related to keeping the ball in the pocket. Bowlers with lower averages would want to focus on hitting the headpin and increasing the first ball average as a priority. It isn’t that practicing spares is less important, it is that honing the targeting process down that results in higher first ball counts is easier to measure and see progress with even when the average isn’t quite following along.

If you hover over any measure it will give you a “player card” that contains a violin plot with their games and their average. In this case the median and the average are the same. They can be different and this tells us something about what we can expect from different bowlers. You will note here that the plot distribution is weighted slightly below the average which means I can expect games in the 160-175 most commonly from this bowler, with occasional games well over 200 to balance the average higher.

Now lets return to our 171.5 median bowler with a GOAL headpin % of 91.39%, a GOAL single pin spare percent of 69.77% and a goal 30 point average of 0.93.

The Practice page allows to to review this information in more detail and to see trends over time. If you click on the bowler whose measures we are reviewing on the Goals page, you will see several boxes at the top. In the business world these are called KPI’s (key performance indicators). The overall measures merge the practices together. The trend breaks it out by practice. They look like this:

practice_measures

practice_measures_trend

Notice that their headpin % is exceeding the GOAL and is thus green, the single pin spare % is exceeding the goal which is also in green. The only measure that is not exceeding the goal is the 30 point average. This lets us know EXACTLY what the priority should be in practice.  As a note, when the bowler is very close to a goal, the measure will be yellow (their Fill % goal is 77.1%).

Now the Practice dashboard can be used for a variety of other things. Below I will explain the different sections of the dashboard:

practice_dashboard_overall

Slicers

  • At the very bottom on the left there is a pin deck with all 10 pins on it. You can click on any pin and it will narrow the dashboard to leaves containing that pin.
  • At the very bottom in the middle right, there is a slicer that lets you narrow by the First Shot count. For example, if you want to narrow your analysis to single pin spares you can click the 9 and it will only show frames where you left 1 pin.
  • In the bottom right there are slicers for Gender, Bowler Name and Practice Date.

Sections

  • Games – The games section allows us to look at individual games in the practice sections. Clicking on a game, or a practice date will narrow the other visuals on the dashboard.
  • Converted Pin Percent – This shows the converted pin percent’s as pie charts for each pin in the set.
  • Most Commonly Left – This shows which pins tend to be left after the first shot.
  • Outcomes – This shows what happens in your frames and a count of how many frames you are analyzing. For example, if you want to look at convertible spares that you miss you can click on the Open adjacent to the Convertible.
  • Most Common Spare Leaves – This shows what types of spares you are leaving. Multi-pin spares are more difficult to convert than single pin spares. If you are leaving the same types of spares regularly, it likely tells us some things we can do to leave those less.

The best thing I can tell you do to is simply click around on the dashboard. Below I will highlight a few examples of the types of things we can see from the dashboard.

Most Commonly Left – a few case examples

most_commonly_left_examples

These examples are for a right handed bowler. Each of these tells us something about what is happening on the lane even though we are not there.

  • A – ball is hitting the headpin and travelling through the pocket. The 10 pin should be the most common leave for a right handed bowler.
  • B – When a 2 pin is the most common leave the ball is going through the headpin to the right and is thus *light*.
  • C – When a 3 pin is the most common leave the ball is going through the headpin to the left and is thus *high*.
  • D – When the 5 pin is the most common leave the ball is often missing the headpin entirely. In this case we see that the headpin is hit sometimes but that frequently some combination of pins on the right side of the lane remains.

 

Converted Pin Percent – example

converted_pin_percent_example

With the example here I narrowed the dashboard to shots where 9 pins were hit on the first shot to analyze single pin spare conversions. The example above is a possible indication of someone who is comfortable with single pin spares that are in the line of their strike shot. Notice the trend of higher conversion percentages near the pocket.

 

These are just a few examples of how you can look at the practice dashboard to get an idea of how to improve your game. The coaches will be looking at it but there is no reason that you cannot assess your own game. Let us know if you see anything interesting in the dashboard that can help make our team better.

Please note! These forms must be filled out by each student before you can practice with the team or tryout. Returning students who had a physical last season still fall under their previous seasons physical until October 1. 

 

Tryouts for the girls and boys bowling teams at Denham Springs High School will be at 3:30 pm Sep 8 & 10, 2020 at All Star Lanes in Baton Rouge, LA.

Open to all Denham Springs High School and Denham Springs Freshman High students. No bowling experience needed – just a desire to have fun, work hard, learn, and be a part of an amazing team!

tryouts2020-2021

Do NOT think if you have never bowled before that you do not have a chance to make the team. The last two seasons we have had high performers on each team that had no experience before the season began. 

For tryouts you will bowl a total of six games. This is a varsity sport and we are a competitive team. Making the team will be determined by a combination of:

  1. Scores
  2. Commitment
  3. Attitude
  4. Potential

For each match we are allowed to have 10 members dress out and be on the roster for both the girls and boys team. We can have more than 10 make each team but only 10 have a chance to compete each match. Last season we were able to carry a JV squad which gives another 6 to compete for a shorter schedule during the bowling season.

 

*** PLEASE NOTE! There are LHSAA COVID-19 guidelines that we will adhere to for practices, tryouts and when the time comes, matches. ***

Current LHSAA Covid-19 guidance

Please read through the guidance linked above. It is critical to note that the safety of the students, parents and staff are primary.

Also, Group C students are not allowed to work with the team until such a time that they join their Group A and Group B peers at school.

As we have all become accustomed to, this schedule is subject to change based on future COVID-19 related realities. Stay safe and we hope to see many of you trying out in September. 

I decided to put this together for the spectator of high school bowling teams in Louisiana. It will give you a summary of how the games are scored and what is meant by certain terms you might hear discussed while watching matches.

High school bowling is a scratch competition. Scratch bowling means that there are no handicaps. In traditional league bowling there is often a handicap added in to allow bowlers of varying skill levels to compete at a similar level. With a scratch competition the scores are simply what you see on the scoring machines. 

In a match there are six bowlers per team and a match takes place on four lanes. Six bowlers on each team are divided into two groups of three bowlers on a “low” lane and a “high” lane. There is a total of twelve bowlers competing on the four lanes. The layout between the lanes will look something like this.

lane_setup

The H stands for “Home”. H6 will be the highest average bowler on the home team and H1 will be the lowest average bowler on the home team. The V stands for “Visitor”. Typically you will bowl your best six bowlers. They must be in the lineup in average order from the lowest to the highest when determining head to head wins. Coaches have the option of making substitutions between the games but the relative order from low average to high average must be maintained.
 
At the end of each game head-to-head wins and losses are determined. There are a total of 6 points to be earned this way. There are 2 more points that are earned based on the game totals for all six bowlers on each team. This is called total pins. Therefore each game is worth a total of 8 points.

At the end of the match total pins for ALL games is used to earn another 3 points.

So lets summarize …

6 bowlers x 3 games = 18 points in head to head matches
2 points x 3 games = 6 points for single game total pins
3 points x 1 match = 3 points for overall total pins

18 + 6 + 3 = 27 points which can be earned by teams. Ties result in a split 0.5 to 0.5.

H = Home
V = Visitor
Bowlers 1-3 are on the “low” lane
Bowlers 4-6 are on the “high” lane.

High school bowling is spectator friendly especially with automatic scoring computers because you can always know what is going on. You can simply compare the ongoing scores to each other and know roughly where you stand throughout the game. The total pins are typically available on the lower right of normal computer scoring systems to give you an idea of whether you are on track to get the two points at the end of the game or not.

That is really all there is to it. Now you are an informed high school bowling spectator. Enjoy the games.
