Difference between difficulty settings?

[econ21]

Verty interesting, Hoof. Do you know how a level of experience difference would affect the combats on medium?

The reason for asking is that I vaguely recall expert in MTW gave the equivalent of +1 valour, more or less. That seemed about right (particularly given the big bonuses you could get for general command stars).

Your experiments seem to show a bigger edge than that in RTW, but to be sure one would need data on the effects of experience differences on medium (i.e. fair) comparable to what you have produced here.
