Anyone know where to find correct ias/AF frames for Impale on patch 2.4/2.5?

I seem to get different results in Maxroll D2 Planner, d2.lc ias calculator and warren1001.github.io IAS_Calculator

With -10 mat javs:
-D2 maxroll planner shows 89ias needed for 16 anim length / 10 AF
-D2.lc shows 92 ias for 16 ticks and
-Warren1001 ias calc gives 92ias for 13FPA (total anim length I guess)
