I dont know the inner working of the combat engine so i cant say this is correct, but my observations from doing quite a few tests on the combat engine is as follows.
Arty CV is more often than not, wildly inflated in its "initial" CV in combat reports or rather what its shown as. As in the case of the first battle. IMO u shouldnt account the CV for arty "at all" if u wana find the correct values of ur CV u should "manually" discount their CVs generally speaking.
In the case of ur two examples, while not detailed, that would have helped, i see the following happening.
Inf rifle div initial CV 29. Arty 89. Discount the arty. So the hex has 29 CV. Times 1.5 half for succesfull leader ship tests = 44. Double that as u have fort 1 left = 88.
Thats damn near the modified CV post battle of 84, presumably u had some disruptiosn and the 1.5 for leader ship roll is ofc varible, so u cant use this as a hard number Still, my explanation seem possible so far.
Inf Divs initial CV 28, discounting the art CV, times 1.5 for succesfull leadership rolls = 42. No fort post battle this time to modify CV so u have end with 42, vs actual modified CV of 55. Obviously there is a difference there between the 42 and the 55, but remember that the 1.5 is just a number "randomly" set by me. What the actual leadership rolls modification are, differs depending on succesfullness of the actual roll.
So presumably the reason u get a held and 88 in modified CV on the first battles, is IMO most likely from the doubling of the CV u get from the fort 1 left post battle= the modified CV. Which isnt there in the 2nd combat and this accounts for the different modified CVs in battle 1 and 2. Hench this the reason why u lose the 2nd battle. It prolly has nothing to do with the arty CV. Also the hidden factors cuz i dont see the detailed report is what the disruptions are in the 2 battles. All things given u will have less elements in the 2nd combat, some being damaged/destroyed in the first and higher fatigue as disruprtion from teh 1st battle is converted to fatigue after the battle.
I have found if u look at many many battles with this in mind the explanation i can come up with is the CV that arty no matter what it might say in the initial combat reports. Is that it contribuates with insignificant amounts of CV, in line with the actual CV the unit has, when u check its CV out of combat.
This btw doesnt in any way mean that arty is useless. If properbly used and under rigth circumstances it can cause huge amounts of disruptions lowering the enemy modified CV, it just doenst have much of a positive CV effect for ur own forces.
