Hi there, thanks to maintainers’ efforts to rdps statistics in FFlogs. The method that divides rdps contribution among damage buffs is truly smart.

Nevertheless, a player discovered a matter in the method that divides rdps between damage buffs and crit (or direct hit) buffs.

In conclusion, current method tends to underestimate contribution from crit and direct hit buffs while overestimate damage buffs when they are combined. He presented here.It’s in Chinese, I will summary here if you would.

Considering two conditions

C1.Mary, whose crit rate is 160% and base crit chance is 30%, casts two Glare, both would hit for 1000 points if Mary had no buff. But a Glare is buffed by Trick Attack, the other Glare is buffed by Chain Strategem and is crit due to the buff. So Mary hits for 1000×1.1+1000×1.6=2700 in total.

C2.Mary also casts two Glare, this time a Glare is buffed by both Trick Attack and Chain Strategem and is crit while the other one recevied none. So Mary hits for 1000×1.1×1.6+1000=2760.

In C2 Mary hits 60 points more, it explains why we should allign several buffs —— the extra hit points are from combination of buffs, thus they should be divided among these buffs. But current method owes

them all to Trick Attack.

That says, Trick Attack takes 1760/1.1×0.1=160 rdps first, Chain Strategem takes 150 rdps then in C2. But in C1, where Trick Attack and Chain Strategem take effect separately, Chain Strategem still takes 150 rdps while Trick Attack only takes 100 rdps. Trick Attack takes all extra 60 points from combination of two buffs. It seems Chain Strategem suffers unfair treatment in such method. So as other direct hit and crit buffs when they are combined with damage buffs.

We put forward a modificatory method when a crit or direct hit event happens.

In C2, when the 1760 hit occured, we divide it into two parts.

The first part is 30%/(10%+30%)=3/4 of the 1760 points (1320), which are independent of Chain Strategem, it is caused by Mary’s own crit attributes. So Trick Attack takes 1320/1.1×0.1=120 rdps here.

The second part is the other 1/4 of the 1760 points(440), which shall be regarded as crit Chain Strategem brought. In this part, we take Chain Strategem as a 60% damage increse buff. So Chain Strategem takes 440/1.76×0.76×lg(1.6)/lg(1.76)=157.97 rdps here， while Trick Attack takes 440/1.76×0.76×lg(1.6)/lg(1.76)=32.03.

In this method, Trick Attack takes 120+32.03=152.03 rdps in total, Chain Strategem takes 157.97, Mary has 1450 remains as her own rdps. By the means it looks as if we succeed in alloting extra points

between Chain Strategem and Trick Attack.

Look forward to your comments
