The variance in potency is negligible, especially when compared to the variance in potency of LSD doses. It is generally known amongst those taking mushrooms that 2 - 3 grams is within most people's comfort level.

This is why a responsible mushroom grower will thoroughly dry their mushrooms before consuming them.
