A good idea would be: you get 1/4 of the soldiery tomes you didn't get last week to the new one.

Ex: If you have 50/450, next week you will have 0/550 from the start.

If you didn't any of that 0/550, you would receive more 112 (from the 450) next week and not 137 (from the 550).

So next week 0/662.

Eventually you will get to a forced cap of 1100 or something like that.

I think it's a good idea.
