Say CS, and DS each had a 30% chance to crit (either they Crit or they Hit, no miss/dodge/parry etc.), which means Judgement has a 48% chance to crit (due to talents). So, (0.3+0.3+0.48)/3 means RV has a 36% chance to be applied. Out of that 36%, only 5% of it will crit. So off of each attack roll, there is a 1.8% chance that a RV crit will occur.
Note: I forgot to see if RV critted as a 1.5x or 2x multiplier on the PTR: We'll find out eventually.
