Description of the problem being solved:

The Bifurcated Crits calculation was incorrectly using the chance that a hit is a bifurcated crit to calculate the average crit damage increase instead of the chance that a crit is a bifurcated crit

e.g. With 50% crit chance and having a Bifurcated Crit source
25% of the time will have no crit
50% of the time will have a regular crit
25% of the time will have a bifurcated crit
but a 33% chance to have a bifurcated crit given that the hit is a crit already (25/75)

We were using the 25% as the crit effect multi, instead of the 33%
