Bat question

The reason the bats with the 2013 stamp are allowed in the male FP game is that field studies were done and with the average swing speed in that game, the bat still meets the exit speed standard of 98 mph.

It was my understanding that similar studies were to be done in the female FP game to determine if the 2013 bats would be allowed. To the best of my knowledge those studies have not been done or the data is still being analyzed.

That is correct and the answer to Crabby Bob's question. they had the data to show swing speeds and batted ball speeds were acceptable in the men's game. They are working on getting the data to prove it's acceptable in the Women's and JO girls game before allowing it. They are very data driven in making changes to bats and balls!!

While "they" may be very data driven, doesn't logic presume that the females' average swing speed would be slower than the males? And averages being what they are, there are undoubtedly some females that have a higher swing speed than some males.

Also concerning averages, if you're knocked silly by a batter with lower than average swing speed, it's not going to hurt any less. (Although I think that's why the new ball was introduced - less damaging when contacting a human head.)

If data driven to safety concerns, why not use the upper 2, 5, or 10 percent of swing speed to derive the "average".

Favorite piece of knowledge shared by my statistics professor: Statistics is a lot like a pretty girl in a skimpy bikini... You may see a lot, but you could be missing the most important parts.

By logic, yes. By process of science, no. Extrapolation outside of the data range is a sin.

You know, many have never seen a ball at 98 mph. Fast is fast and we think of bats as "hot" or "hotter", but totally based on what one has experienced.

98mph is the maximum exit speed and if you see the max, IMO it is more likely in a SP game as FP is more about contact then power, in general.
