Agreed.
Need to factor in the near-190 roll rate, improved engine power, etc. I suppose it might be marginally "worse" if you are considering it from a pure, flat turn perspective but adding those other factors in it becomes the most maneuverable of the Spits.
The spit 8,9,16 all have basically the same turn rate and sustained turning circle, and they are all significantly better than the seafire. On the list spit8 is 21, spit16 is 22, spit9 is 23. But the seafire is 37 better than the la5(38), but worse than the la7(36). The spit14 comes in at a mind boggling 50, worse than the tempest. Which completely contradicts RAF tactical trial reports.
It seems that aircraft weight makes a HUGE difference, as evidenced by the seafire(37) vs the spitV(14) and by the 202(30) vs the 205(60).
