This article is from the USBC study done in 2007.The Article By Nick Siefers.
I could not find the article on the Bowl.Com site,but I'm sure it's there
somewhere.I found this copy on Bowling Digital.Com
Most my have seen it before,but I'm posting it for the use of the rest that
may have not yet read it.It is a very long and detailed study.
