Campaign Experience

[Imp]

Would it be possible to have a box similar to repair points for experience gain in campaigns?
As in say normal 2/3rds 1/2 1/3 1/4 or similar.

This may be to complicated as looking at things I think the base adjustment for turning up is not to bad its the rewards for being involved in battle such as a kill that boost to fast.
Though could just do on the whole thing for ease nice way would be to really slow progression once reach 80exp or so.
German Long Campaign 45 battles 5 battles in.
Start experience 75
Think my HQ has gained about 3 exp unsure what he started with FOO has gained 2 started high with 79.
Combat units few high 70s but most are 89-93.
Say average 90exp so troops getting kills are averaging 3exp points per battle.
While it is nice that my artillery now all has 1.2 call times & my tanks are pulling off great shots they are to good for my idea of reality.
Just my view but units with experience in the mid 90s are to good especially at spotting the enemy.

This is not high priority I can just sell off & replace 2/3rds of my force every 4 battles or so.
