Why would anyone link the name of a rank to the size of a squadron? Even if it was linked just what kind of role would we even be talking about - logistics squadron, engineering, admin, flying, ops, ATC, Int et al?
As an aside back when I was a sqn ldr flight commander I had just over 100 personnel, mostly aircrew. It also just happened that you had to be at least a squadron leader to run the squadron at home or on ops. Many moons ago I ran a small collection of aircraft in the Falklands. We were known as a 'Flight', as was the other fixed wing flight next door. The third flying unit was rotary, similar size and commanded at the same rank but was known as 78 Squadron. None of it really matters.
