The GM might allow you to roll the dice twice and double the modifiers, bonuses, and penalties instead of doubling the entire result, but this usually works best for single-target attacks or spells at low levels when you have a small number of damage dice to roll.

seconded. statistically, there IS a difference between rolling 2d6 versus rolling 1d6 and then doubling it.

the results of the first method (the PF1 method) are a bell curve, with low and high numbers less likely and numbers near the middle of the range more likely.

the results of the second method (the PF2 method) are a flat distribution, with all results equally likely.

Well, to be uselessly pedantic, the results of the second method are indeed a flat distribution, with all non-odd results equally likely. :D

I believe it is on the list but not the highest priority.
