I'm only 5 innings into my 1st game with these sliders, so I won't claim to be an expert. But, I am already seeing a difference. I've had a double play blown by my SS's throw pulling the 1B off the base. Had another one almost pull him off again later on.
It looks to me like the meter loses most of the "green zone" if your guy is on the move and it comes back if you take the time to gather yourself and throw. I really like it thus far....though again, only halfway through game 1.
