1.13 secs seems like a lot.
Why not teach the runner to leave when the ball is 1 ft from being caught. If you like the 1 ft thing. Yes she will have to stand with her shoulders sideways on the bag but I don't think that's a big deal. You've got me thinking. Gonna run some tests tomorrow. Time the kids me saying GO, kid reading ARM drop, kid reading the ball.
I can see how it would be faster for the coach to signal "go" as opposed to the BR watching the ball into the outfield while on 3rd base.
I am a control freak
