Why are you so bothered; if you're keen on joining, you only need one.
I'm sure we recruit something closer to 120 a year, and aim to produce something like 40 fast jet pilots into productive service in a year.
Valley courses start something like every 8 weeks, and if it was a course of 4 it was probably a 19 Sqn course. They're smaller, because a lot of RAF guys go to NFTC instead, not to mention poor creamies.
