do you know how to calculate standard deviation within your spreadsheet? if you had standard deviation then you could make claims like "when playing by skill, 90% of the time you'll score between 200 and 260". if you can post the standard deviation for each data set then i can give you the english equivalent. it'll give you an idea of how much variability is in each data set and how unusual each score is (i.e. how rare is a score of 121 when playing by skill? maybe it's only a 1/1000 thing)
yes, you are a loser. i would do something similar though... of course, i would probably simulate the dice rolls with the computer rather than playing 100 games per data set... urg... that's some dedication ;)
