I tried having one run with all CVs in 2-3, out of 24 squadrons sortied, 4 of them gained one mark. 3 of those are 601-related attacker planes who has default 1 mark, the last is Reppu-kai.

I think we can conclude that gaining marks is related to actual contribution. So be careful if you sortie a bunch of rookies with an ace, the ace may end up getting all the credit, stopping those rookies from leveling up.
