And I thought in the simplified simulation that the game uses 5000 men per level of fortress were necessary to actually siege and fewer could only cover the fortress.
my game has 3000 and I have not amended anything
Most armies had a supply train which slowed them down and in most wars armies that operated deep in enemy territorry suffered from leaving the vicinity of their operational base. In the timeframe from 1419 to 1820 no army should be able to strike deep into enemy provinces far removed from their own lands without losing men like a snowball in the sun. Even Napoleon with several supply depots could not operate deep in russian territory for more than a few month - and the russian winter is only one of the factors that defeated his Grande Armee.

supply trains/wagons went with the army and had a contingent of men to resupply the wagons as they moved, there was no supply line.
Basically up to Malborough who lived off the land while attacking Bavaria , the supply wagons was in use.
There was *always* attrition - even under the best of circumstances soldiers died in skirmishes, from diseases, desertion or marching. That attrition rises much higher under certain conditions is only realistic for the whole length of the game.

I am saying a number 10 for winter is Ok, but an equal number 10 for supply attrition is silly, it has to be much lower. It makes NO sense that they are the same.
Or asking the other way: Do you really want states being able to march their armies with the same ease in their own provinces where they can be fully supplied, in neighbouring provinces or on the other side of the world?
Has it been tested?
I think a ONE province limit for supply ( ie only your neigbour) is silly, at least make it a 2 province depth
