they're all nine out of ten anyway, right? the two percent differences in my eyes are insignificant. beside there are many factors ignored by those statistics. who stops firing after one shot? how do they really know how many times a single shot failed? any time a single shot failed, and it's possible many shots failed, that data never makes it to the study. go with your gut and keep it simple, bigger holes. don't get me started on hydrostatic shock.
