yes, the 190 and F4u have nearly the same 'rate' of turn, but the Corsair does turn inside it and can hold a firing solution. The 190 should always use the vertical to cut across the circle or else force the F4u to bleed even more E in lead pursuit. Lasz, in that report, the inital speeds are not given so we don't know anything about the initial turn rates or G loads. I believe that the relative performance for a sustained turn is accurate though. Clearly, the 190 can't pull as many G's as the F4u from a fast attack speed (300+), but in a sustained turn, the G's are about the same (the Fw flying the circle faster).
