Slow the game down was developed by Dr. Bill Harrison. He has worked with alot of players and teams. Wrote some books ect. https://www.slowthegamedown.com/
I use his 3D perception app, cards and stickers, the eye tracker and small ball/small bat. I use a different small ball machine though. I have a couple "personal pitchers" http://personalpitcher.com/...rather than his max bp.....that I use.
