I don't think pitching velocity is a "garbage" thing created by dads. Velocity is *one* of the factors associated with successful pitching. We can all name several others - location, changing speeds, deceptiveness, etc. Success with one factor can make up for deficiencies in other areas. As velocity increases, it can make up for many other deficiencies. My experience is that scouts created the quest for 90mph, not dads. Having gone through the recruiting process with a pitcher I know that's one of the things that is heard constantly from most of the "baseball" guys. As a pitcher's dad hoping for big things for your son, 90+ is something you long for for the kid. It's one of the milestones. And why shouldn't it be an ego thing? What's the pct of HS guys throwing 90+ ? If I could do it I'd probably stick my chest out a little around the ball field. If I could hit it, I'd stick my chest out too.
As to the guns, the stalker has a setting to record the highest (out of the hand) and the lowest (crossing the plate) speeds, so you can tell the difference. I don't try to time "getting of the trigger" as DownTheLine suggests. I disregard readings when the ball is hit for exactly the reasons he indicates. The ball often comes off the bat faster than it came in and that's not what I'm measuring.
I didn't have my gun out at the Heath game but I sat beside pma earlier in the year to compare the stalker and the jugs. On that day our guns almost always recorded the same speed so I believe his to be calibrated. Occasionally there was a 1 mph difference, his (jugs) being the faster.
I know that pma was directly behind the plate and the second gun mentioned was at an angle. What difference does that make you ask? Just look at the stalker owner's manual. "The most common mistake made with all radar guns is trying to clock targets at angles. Clocking at an angle will result in angle error, and the gun will display a speed that is LOWER then the actual speed."
How much difference you say?
100.0 mph
at 5 degrees 99.6 (0.4% err), at 10 deg 98.5 (1.5% err), at 15 deg 96.6 (3.4% err)
at 20 deg 94.0 (6.0% err), at 25 deg 90.6 (9.4% err), at 30 degrees 86.6 (13.4% error)
That second gun may have been at a 15-20deg angle accounting for the different readings. See picture.
I would ask if the 89 reading was an "outlier" or consistent velocity? If everything else was 84-86, I wonder about that one.
Anyway, Heath won and advances.
Apologies to all for having too much time on my hands.
