Well, obviously it depends on your file turnover rate. [;)]
Two things that may console you. One, a lot of every huge-map campaign scenario (388 turns Waterloo, 534 turns Eckmuhl) is marching, so if you have your columns closed up and organized correctly, it's just a few clicks per turn. If you and your opponent agree to rest at night, these turns pass ever more quickly.
Secondly, it hardly ever takes 4 or 6 days to reach a conclusion. I have completed several huge Eckmuhl games. I believe the longest (with Ed Blackburn) was 175, one with Rich Hamilton was 120 or so, one was over after 65. I am in a Waterloo campaign game that is at turn 100 and even though another major battle is still possible, it will take place in a location where it must decide the campaign, so this can't take forever either.
