I heard they count each a/c in a flight as a single operation. So a flight of 4 gets counted as 4 separate. Idk tho, this is just what I heard when I was in and that they aren’t that busy.
Fwiw, I was at one of the slower RAPCONs for 5 years and then Korea for my last and I got a few standalone TRACONs like U90, Y90, A11, and maybe a few others then a bunch of 7s and below on a list of 35ish facilities. So you probably will get higher levels (8-10) but the list will consist of mainly 7s and below. Last lvl 12 I saw on a list was a guy from Nellis and Osan and he got offered P50(not sure if they’re a 12 or an 11) but he didn’t get it. Got like FSM or some low level facility in Texas.
