I was wondering, I've never really looked into it, but I imagine there is a statistical significant difference between using a 1d100 and 2d10 for rolling a 0~100 number in this system. Both in real world and using computer based random generates for dice (rollers). I can't imagine they are really worlds apart in terms of the average they roll. But I do think they have to be different, because taking the average of a 1d10, twice, is quite different from a single 1d100 average.
I'm not looking for power play or using a rolling system to improve averages. Just looking into for the sake of interest.
