Calculation of the crit multiplier

Hello!
I want to show the calculation of the factor in the crit bafe Priest

Calculation of the crit multiplier

R = x / (((y-x) * 100) / k)
x - Done with no crit buff priest (consider the average value of at least 10 and crits, need to hit the target with armor tends to 0)
y - crit damage from Baphomet priest (consider the average value of at least 10 and crits, need to hit the target with armor tends to 0)
k -% extra crit damage buff priest

Thus it was established, in particular, that the crystal crit 13 with fishing combined with Baphomet Priest
I hope it will help people overclocking the crit
I turned the coefficient of 2.31

I don't understand anything
