Well that's simple to say. But once the "rivet counters" (I seem to have become one lately
) have spent time analysing the historical record, then developed (valid) competing arguments which give a range of performance, what would you do? Pick your favorite rivet counter?

Well I would grant the reds the 100 octane performance data. I'd give the 109 the factory data. I would certainly adjust the roll rate of the padal winged spitfire.
Folklore and stuff in books by any pilot would be pretty much out of the window. Sorry Notafinger... However I would include the percularities of certain aircraft, like the 109's port wing stalls first near the stall etc.
As for random degress of performance in an aircraft, I'd say no...

I agree with you on speed (haven't looked at roll issues). Would you give the factory
average spec for 109s (it is +/-5%) though? My analysis suggested that would be OK for 5000m but a bit optimistic for sea level (Not that you have to use that
)
I would think that period pilot reports would rank higher than folklore but lower than flight tests when considering historical sources.

I calculate TAS as 2% greater than IAS per 1000ft altitude using this link (
http://www.csgnetwork.com/tasinfocalc.html), there may be a more accurate calculation out there.
I just did some altitude speed tests offline (beta patch), they are OK for 109 but a bit horrifying for the RAF as they are below the B6 patch curves. I tested for full Throttle height (above which boost declines at full throttle). My assumption was that top TAS should be around FTH.
109E4 (prop pitch control on)
FTH: 5000m (boost has dropped a bit to 1.32ata, declines rapidly above 5000m)
425kmh IAS@5000m =
569kmh TAS, exactly right for Messerchmitt official average spec.
Spit Ia
FTH = 16500 ft
at 6.25psi, 2750rpm (rad open) engine fails after about 3 minutes. Just enough time to get stable 245mph IAS (with 3000rpm couldn't get this alt without engine death)
245mph IAS@16500ft = 323mph TAS =
520 kmh TAS
Oh dear, this is under even B6 plot speed (560kmh TAS at 16500ft).
Spit IIa
FTH = 13500 ft (?!)
at 6.25psi, 2750rpm (rad open) engine fails after about 3 mins
260mph IAS@13500 = 328mph TAS =
528 kmh TAS
I really hope I making some kind of testing error here. Tried online and got same values. I wouldn't feel confident taking any Spit against 109s at alt with these values.
