First: WAAH. Second: your post contributes nothing, and even if it had, it replies to another post asking for handholding.
Sims for fire are terribly off anyway. They just can't model ideal combustion setups. But adding 10% on top of whatever Simcraft shows has been pretty damn close for me. My 92k simcrafted gear did 101k to Feng for example, and it wasn't some crazy "60% crit rate!" RNG fest.
But the changes should be in 510-3 whenever its available. You'd have to sim for BIS because all our current gear is of course completely wrong for Frost.
