I think your results agree with the DPR analysis more than those early posts indicate. DPR should give you the MEDIAN number of rounds, which is the point when you win 50% of the fights. For example, in your first graph, the one with DPR giving 4.6 rounds and the MC giving 5.5, 57% of the fights are over by round 5.
It makes sense that the mean is skewed high. Variation from the average can only shorten the fight so much - it is going to take at least 2 rounds to kill that soldier. But on the long end, the fight can go long as 13 rounds. The 13 is going to pull things high a lot more than the 2 pulls things low. This same effect is why home prices are usually listed as median home price. One millionaire throws the mean out of whack.
Interesting project!
PS
Right and if you look at his curves they are basically pretty much T distributions. Its exactly what you would expect and you could derive the numbers analytically vs using the MC method. It might be a bit faster, but OTOH I for one am both lazy and would have to brush up on some advanced statistics...
