Throwing some light on rates of turn

[Talisman]

Having been out turned by a Me 109 E a few times when flying a Hurricane, I decided to check my CloD control calibration (green bars for input and output) and found that I was not getting full elevator deflection.
After giving the joystick some vigorous movements, full forward and back a few times, it appeared to reset to my original settings with full deflection. This seems to happen to me on an intermittent basis (when flying Me 109 too). I suspect that it may be my joystick, which is rather old now, so I plan to order a new one soon. I keep checking my elevator deflection now as I am unable to trust to it. Hope the new stick solves this issue for me. Perhaps others may be getting the odd glitch with elevator calibration too.
