I think outlier needs to be a toggled setting (similar to holding a button to slide step) that allows the P to reach back and put a little extra on their pitch at the cost of stamina. With the exception of like a handful of relievers and Greene, no one throws 100+ regularly every pitch.
It makes me think back to when meter was a main way to pitch....you could let the meter go further to throw a bit harder but at the cost of accuracy and stamina.
