nothing bad about it. just the facts sir.
OMG stop referring to that BAD science!!!!!
You're right! I presented the facts that could NOT be countered.
Thank you.
If you thinks it helps hitting, trust perception over reality and believe your eyes instead of high speed video and physics. But you're wrong to fault the science.
…Some absolutes are the change should be approx 25% slower than fastest pitch, …
Whenever someone mentions “absolutes” in ball diamond sports it gets my attention, especially when stated as the above where the absolute is approximate. What you seem to really be saying is, the change should be 25% slower +- some percentage than fastest pitch.
Being a numbers guy, the 1st think I do is look at the numbers. In baseball an 100mph FB would mean the CU had to be 75mph, and I can tell you that ain’t gonna happen very often. In SB that would mean a 70mph FB would require a 45mph CU. Perhaps that commonplace in SB, but it sure seems to me that there’s something out of whack with that “absolute”.
What you are referring to is what I would call an offspeed pitch and not a true changeup. Many elite pitchers will have three different speeds.
Regarding my statement that the C/U should be 25% less speed than the fastest pitch isn't an exact % but a range. The point is that you want the c/u slow enough to disrupt the batters timing.
