Do we actually know the size of squadrons in the FS universe in the first place? There's really no standard for it in the real world, it varies with country and aircraft type. Same thing goes for fighter wings, btw, that can be anything depending on who you ask - In Tie Fighter for example, I seem to recall a fighter wing being 60 fighters.
I'm fine with canon squadron numbers as they're stated in the techroom and command briefings, but unless clearly stated somewhere, speculation on actual fighter complement should be avoided except in the appropriate sections (such as veteran comments).
