bat testing
I read some bat test data. They used a 6' 1" 220 lb. "experienced" (25 or 30 I guess) player to hit. He hit with a Freak bat a 525 compression ball 102 mph to determine the pitcher's safety. We need a 55 year old batter to determine the safety of a 55 year old pitcher, We're not playing against the young guys. The data decided 85 mph was the max for safety. That excluded all composite bats. How fast can a 55 year old hit a ball? It isn't 102 mph is it?

Where did you see this data? The age of the batter has no relevance. I know of serveral "experienced" 55 year olds with tremendous bat speed.
I would also think that all composites are not alike and that some non-composite bats (PST for instance) are better than some composites (SilverBack or 3DX).

I would think your strenth, timing, etc. would decrease your power and bat speed as you got older; in general.

Mc Donald is well known. I know of a few 60+ players who might equal that speed. One of them swings with one arm.
But if their going to use a young guy for a referance thy should also use an older senior say 65 and take an average. The 65 is by far not the oldest division and neither is the 20's the youngest but at 25 or so, iprobably more beefed up than an 18 year old.

Problem with tjis test is the ball...What association uses a 525 ball. Last time I saw one of these was a NSA Men's in Cali.

The following infor has come from an INDEPENDENT test' lab.
Also,Skins 6, I believe the 102 MPH is once the ball has been hit (BBS).

ASA BALLS: 23 out of 51 balls that were tested failed. Comp, too high.(413-552 PQI)
NSA BALLS: 6 out of 6 balls that were tested failed. Comp, too high.(445-604 PQI)
USSSA BALLS: 26 out of 41 balls that were tested failed. Comp, too high.(411-645 PQI)
A BBS of 85.2 MPH w/ a pitcher stand' @ 50' will have a reaction time of .400 sec.
A BBS of 93.7 MPH w/ a pitcher stand' @ 55' will have a reaction time of .400 sec.
A BBS of 102.3 MPH w/ a pitcher stand' @ 60' will have a reaction time of .400 sec.

In a 2000 reaction test, all ASA's & USSSA's balls circumference were to small.
ANY BALL THAT HAS A COMP over 411 PQI, will reach a pitcher
stand' @ 50' faster than .400 sec.
In 1 test, it was found that heaver balls went 15.9' farther; smaller balls also, traveled farther.
Reverse Rotation grips produce greater backspin & distance, than Overlap grips.
A ball w/ an increase of 150 PQI will travel 6 MPH faster & 20' farther.
4 factors that will effect a balls distance are: 1)Cor 2)Comp 3)Circumference 4)Slippage
40 Cor balls will travel farther than a 47 Cor ball. BBS will decrease 3.57 MPH (-11').
