Ah, I thought that is what they are saying, and thanks for explaining it… but I don’t agree! I think you get much more ‘middle’ numbers with an ordinary bell curve (i.e., 3d6 vs. 1d18) and you’ll skew much higher AND almost never roll a ‘natural 1’ if you pick the highest out of multiple dice. Maybe it’s time to run another ‘Monte Carlos’ simulation on my computer to make the point.
