I find that it takes a while to cycle through my own turn, even by the third month of the campaign game -- at my rate -- roughly 1+ hour/turn it'll take 150-200 hours to finish one grand campaign.
What strategies do people have to speed up this cycle?
One of the things that slows me up seems to be switching between recruitment (and schlepping units to the front) and actually giving orders for the front line units. Have people found ways of speeding up this process?
Should I be doing big boluses of recruitment: i.e. letting my cash and war supplies sit in inventory for a quarter, then spending all of it at once -- of course this means a big work-load when all the units muster, but better doing this once a quarter than every turn.
