Hello Razor
even if many LW pilots thought that a tour lenght of RAF and USAAF fighter pilot was 50 combat sortie, that wasn't true. The limiting factor was operational flight time, 200 hours, for P-51 and P-38 pilots that was more or less like 50 combat sorties, but for Spitfire, P-47 or P-40 pilots clearly more, for Spitfire /Hurricane pilots close to 200 sorties. So some USAAF and RAF pilots in ETO flew appr. 500 combat sorties during the WWII. And in SEA RAF day fighter tour was 300 hours or one year, whichever was completed earlier.

The first ETO tour was 270 hours then extended to 300 hours ~ august 1944. Many volunteered for second tour. P-47 pilots obviously flew more sorties to get to 300 hours than Mustang/Lightning pilots in the 8th AF. For TAC/9th it didn't much make a difference as missions were relatively short range/heavy load.
For my father the first tour (all P-51) was 300 hours and 60 missions. He shot down all seven of his air to air scores in his first 35 missions then never fired a shot after that except at ground targets. He only got in 12 more missions on his second tour which was March/April 1945.
