I copied your excellent mathematics to a page of it's own. But before using it as a reference, please help me check the validity of it. I expanded your table with the case of 0% crit and 100% crit. The 100% crit case seems to show that 20% of the hits will not benefit from improved SB, which is wrong, isn't it? --LarsPensjo 10:02, 15 January 2007 (EST)
