I just looked over the document and considering typos and transcription errors, I'm willing to bet that it should read 3 seconds instead of 8 seconds.

I dunno, remember these speeds are mph not kph, 400mph is hauling butt in these 1940 models!

Actually seeing Banks graph shows 4secs for the Spit and about 4.5secs for the 109 in a 45° bank at 400 mph. For 90° you can double the figures. So it would be 8secs for the spit and 9 secs for the 109 at these high speeds.

Where does the graph come from? Is it original test data or someone who wanted to write a book to sell it?

The following graph is showing roll rate of the Spitfire Mark V, with fabric covered ailerons, via J. Smith -The Developement of the Spitfire and Seafire, Royal Aeronautical Society.

The Mark I and Mark IIs we have in the simulation had fabric covered ailerons, so roll rate should be identical. It appears our Spitfire I and II have the roll rates of the metal covered Spitfire's, which is incorrect, as none were fitted with metal ailerons until about May 1941.

Bearing in mind the figures are for a 50lbs stick force, how is it possible to reproduce these conditions in a simulator when there is no mechanical simulation? how is it possible to tell you are applying the equivalent of 50lbs on your gaming joysick? I would say 50 lbs in nowhwere near equivalent of a full deflection at the higher speeds which means being able to apply full deflection in the sim will give higher roll rates than the calibrated data.

Pilot's strenght and stamina plus a well modelled Anthropomorphic Controls setting (so that you can use 2 hands on the stick).

Not really, it's meant to be about the fidelity of an aircrafts FM, the pilot does not form part of that.
what I'm saying is simply to compare the roll rates in sim vs recorded test data when it involves calibrations such as physical force is practically impossible unless you are using a professionally built simulator with calibrated feedback through the controlls, force feedback on a gaming joystick is a gimmick to provide immersion but is in no way a true representation.
