Cross threads have been posted on the repair points balance problem when PBEM Campaigns first came out, you may have been one of the posters.
I did the no expanding core thing but with a few campaigns under my belt now as it stands it makes little diffrence.
If you do not use house rules & one side loses considerably more units the total outcome is decided.
If you win the first battle you will probably be at full strength for the next & so on.
As you are going to take less losses than him once you are a few battles in you just convert your repair points store to aux units & hit him with a huge force, only thought of recently.
A better solution instead of keeping the turns low would be a reduced victory requirment for the game to end early & modifying the repair point allotment in my view.
I actually find trying to withdraw hang on to what you have one of the best facets of PBEM campains as you tend to just go for broke in battles.
