Radius being just one parameter of turn performance and not the most important either.
Not specifically. It appears to be RAM power because the chart list's power in flight.
Exactly, once the parameters are input, the math does it's magic.

Er the chart above also shows Sustained G for any given IAS....at pretty much any IAS the Spitfire can sustain somewhere around 0.5G more than the BF109 ..... (not hard to determine turn rate here either)
The Blue RAE chart (from the same document) also shows sustained G, Turn times for 360 and also provides a means to determine Ps for bleeding turns ..... So we have turn radius, turn rate, sustained G (Ps=0) and a means to determine -Ve Ps values for energy bleed .... what more is there to turn performance ...... give us a break !
So far you have admitted to a weight error in your calculation. We know you made an error on the Spitfire power as well using 950/990BHP whilst RAE used
1050Hp at 12,500ft .... and we also know that a Merlin II power rating at Combat power was
1030hp at 16,500ft as detailed in the 2 seperate Inspection and test certificates.... shown earlier. And in Post 209 with respect Spitfire BHP you said "I suspect it was for an improved high altitude version".... when we know it wasn't and that RAE used standard Combat Power ratings.
