For the 109G the aircraft data sheet says that landing from 20m altitude takes 350m until touchdown. In landing configuration you're supposed to glide in at 180-200 km/h indicated air speed, touchdown at around 160 km/h. This corresponds to a glide ratio of about 1/8.
I haven't been able to find this figure for a 190, but generally landing speeds for a 190 were about 20 km/h faster, and roll out distance pretty similar, so I'd expect something similar. It would be interesting to see what the glide ratios of 190 and 109 are in game, landing configuration, 0% throttle, at 220 / 200 km/h.
Changes to the flight models are generally made to improve realism. In case of the Spitfire IX, this mostly changed handling, with the Spitfire V, both performance and handling were effected. It appeared that the Spitfire needed considerable nose down elevator to fly level over most of the speed range, and this is something we now have in game. This is based on test data and I think you'll also find this on the vast majority of photographs taken of Spitfires in flight.
