That logic doesn't work very well. The P-47 FG were fighting the same mix of LW pilots in Q1/Q2 1944 as the Mustang fighter pilots and were flying many more sorties per day. The basic comparisons remained the same but the P-51 flew longer, flew deeper and were a match or better than the FW 190/Bf 109 at all altitudes.By the time the most of the fighter groups had converted to the P-51 the Luftwaffe had lost most of their best pilots and their planes were being flown by inexperienced pilots some of them just out of school. This could explain why the P-51 had a better kill/loss ratio than the P-47.
Additionally, beginning late summer 1943, the LW realized the existential threat the 8th AF posed to critical strategic targets and began transfer of experienced squadrons from East and Southern fronts into central/east/south Germany, through May 1944.
