The way I see it is like this, I might be completely wrong but it makes sense to me. The big argument between ofc and CCA is the price compared to efficiency in the power they can carry. Electrical efficiency to me is exponential, just like decibels, we all know doubling power will not double your score, the same way doubling your runs will not double how efficiently the runs carry the power. After a point you will be adding 50 runs to only increase efficiency by a fraction of a percent. So after a certain point (like in alpines and HT build's with a large amount of runs) it will not matter if you run cca or ofc simply because the the gain you will see in these extreme cases will be minimal
