Your perception of what I wrote is not accurate. I never attacked TB...TB claimed he was being attacked...I just told the truth about his stake in the game. I produced an alternate point of view with alternate data. I notice you aren't asking the same questions of the LL data that your are of the data referenced in the article I posted. I don't have to prove the "facts" produced by LL baseball, for LL baseball, are inaccurate. The data from the article I posted was derived from an entity that has no dog in the fight. It is against a bat manufacturer's interest to question the LL data.
I have looked at the NY Times
article [nytimes.com] and tried to follow the link to find the Brown study. I did find a Brown University study
here [brown.edu]. (Crisco et al. Med. Sci. Sports Exerc. 2002; 34(10):1675-1684) There is a substantially similar paper
here [brown.edu]. (Greenwald, Penna, Crisco. J. Applied Biomech. 2001; 17:241-252) I've also read
this [kettering.edu]. In the Brown University study, bat W is wood, bats M1, M2, M3, M4, and M5 are metal.
The NY Times dutifully paraphrases
Crisco, et al. 2002...
"
Batted ball speeds. The average batted ball speed was
fastest for bat M2 (93.3 mph) and slowest for
bat W (86.1 mph) (Fig. 2). Bat M2, as well as
bats M3, M4, and M5, with average batted ball speeds of
90.4, 91.7, and 90.6 mph, respectively, were each significantly
faster than bat W, whereas M1, with an average batted ball speed of
88 mph, was not statistically different from bat W.
At a 95% confidence level, the estimated difference in the
average batted ball speed between wood and metal was
-0.7 to 4.5 mph for bat M1, 4.2 to 10.3 mph for bat M2, 1.0 to
7.6 mph for bat M3, 2.6 to 8.7 mph for bat M4, and 1.9 to 7.2 mph for bat M5."
I've taken the liberty of removing metric units in favor of English. There is absolutely no question metal bats can be made to significantly outperform wood bats. The trouble is that four of the metal bats in the Brown study, M2, M3, M4, and M5 are
illegal. This fact is noted in the
Crisco, et al. 2002 paper...
"The bats categorized as -5 and -4 weight-length (bats
M2, M3, M4, and M5 in Table 1) are no longer allowed in
collegiate or high school play in the United States. The
governing bodies at these levels (the NCAA and the National
Federation of High Schools (NFHS)) have implemented
-3 as the maximum allowable difference between
weight and length. The performance capabilities of baseball
bats currently in use at the high school and collegiate levels
are unknown."Brown University is starting a new study of baseball bats. See
here [brown.edu].
Why on God's Green Earth(tm) the NY Times, in October 2006, would not note the fact that four of the five metal bats in the Brown study were illegal, I do not know. To ignore such an important fact, for the sake of selling newspapers, is not merely shoddy journalism but willfully dishonest and reprehensible. Then again, it's the NY Times.
