Against two even players through 1861 to 1863 the CSA cannot really win. Also beyond that it cannot really hold the Union no matter how well the CSA plays. There is no point system I can see that can give the CSA a partial victory...which should be included!
Though the Union Divisions are possible as follows:
Pure Infantry Divisions(CSA has to farm Kentucky and Missouri to get a few Pure Infantry Divisions but the Union can easily recruit these all day long)
20 Pounders... The Union can make these and park them out in devoted Artillery Divisions and it doesn't hurt her to do this. The CSA is fortunate to come up with 10 Pounders..though will have to include old style Napoleon Artillery at best in most of her Divisions. Not that it's not historical it's just the best way to build Divisions.
I think that the designers did not intend to dwarf CSA Divisions, they merely didn't include enough of them in the Build to constraint her manpower but there is no reason why she should be forced to buy Arty/Cav/etc... in her divisions...
The CSA can never win against the Union if the Union knows how to build and is just patient. The CSA probably is doing something to last until Mid 1863(which I see the best CSA players capitulate by about then)
Numbers usually are easily approaching 1.5 to 1 at that point with the very best CSA players... The Template is not any good ... (artillery was superior up north but still)
The ease of which leaders can be promoted(I have had Grant 3Star just now in a MP game in 1861) 1 battle and the loss of 4 NM and a few VPs.. It's a beautiful trade to have him that early! Therefore even the leadership cannot patch the extreme division comparison.
CSA Divisions by late 1862 in the best hands, and leadership melt in front of superior Union Design and I've seen these numerous times. Just wanted to add 2 cents!
