In the scenario DGS, in each frame, the bombers that our (SAPP)'s P38s escorted had the least losses.
Did you have a higher ratio of expierenced pilots, or were you better suited to dealing with the enemies you encountered? And if so, do you still take the lower rate of losses to mean that the P-38 is superior?
I could stack an expert Il-2 pilot aginst a newb P-38 pilot, but the resulting loss of a P-38 doesn't indicate wich plane is better, only that the P-38 driver was new.
Here's another one:
P-51 driver against Ack-Ack in his 38. Ack-Ack's kill on the P-51 doesn't say that the P-51 is inferior, only that Ack-Ack was flying his P-38 against a new or average P-51 driver.
