Hi, at the beginning of the year I was throwing on a line to the plate. However there was little to no "pop" in the glove. Now, my fastball is dropping at the plate, but there is a much louder pop. I am not sure if I am just not throwing hard, or if it has natural drop. I have been more effective recently, so I believe I am throwing harder. Is the pop of the glove an effective relative velocity indicator? Am I throwing harder now or before? Thanks for any help.
