I tried a scorekeeping app on my tablet for a scrimmage and decided to bag it. It was a lot to keep up with. And yes, the game is so sloppy and insane at this age that it makes it tough but the coach really wants data to be able to give feedback to each kid uniquely.
On the video, do you start and stop with the clock? I'm intrigued by the idea. The worst part of it to me would be the time it takes to sit thru the entire game again and record stats. You'd have 3+ hours wrapped up in every game.
Two more detailed scorekeeping question. Does an offensive rebound count as a new possession? And I thought it would be easy to calculate total possessions (Shot attempts minus offensive rebounds minus turnovers) until I realized free throws screw this up...But you can't use FT attempts because of dead ball attempts, so do you keep track of live ball FT attempts to be able to get accurate possession data and rebounding rate calculations? Or am I missing a better way?
The first time I tried to do stats, it seemed impossible. I know kids' seasons aren't very long, but after a few games, I was much, much better at it.
In football, it is normal to pause between plays. Basketball, the breaks are very short, so I'm not sure how much it helps.
An offensive rebound is not a new possession, still the same one. The only way to get an exact number of possessions in a game is to count them, but there is a widely accepted formula used in college that estimates it fairly accurately, counting a free throw as .475 possessions (because a free throw on a three-point play isn't part of an possession). So the formula is FGA+(.475*FTA)+TO-OREB. From there, then you can estimates points per possession. I do this for a local high school league that I do stats for. Some of the coaches think it's really interesting; some of the coaches prefer simpler more traditional stats.
