I know it's already here somewhere...I just can't find i!!

How can I change (increase/decrease) the distances moved by the stategic pieces during a turn?

I want to edit the movement points to reflect reality: specificly naval vessels transiting the med...6 months from Carthago Nova to Rome? Puh..lease!!

I also want to increase the route-march distance for the late Roman legions...

Shouldn't these distances increase/decrease due to experience (getting fitter, better trained) or decrease (Just got served their buttocks on a platter...noobs) in some form of logical progression?

Any help would be appreciated...even a relevant link'd be nice!!

Thanks in advance!
