OK, I get the point about a Sqn not being manned 100% by fully worked up or even fully CR crews. And that has always been the way. It was suggested (actually had been many times) that OCUs could do the full Sqn CR work up. Sometimes we did graduate crews LCR, but that wasn't the norm.
But there is still a big difference between having two complete sets of crews, or two complete crews and having 75% CR, fully worked up.
I think I may have misinterpreted an earlier post. My apologies if that's the case.
