Game Lag and Elevator sensitivity?

[SEE]

There were a number of SIM games last night (Xbox) during which my plane would stall and become unstable, at one point it weaved and stalled in level flight. These games were also 'laggy'. I have been playing BOP since its release and know exactly what elevator sensitivity I need for my a/c so was suprised at just how unpredictable the handling became. I switched joysticks during one match and exactly the same. I had to reduce the elevator sensitivity much lower than normal in order to continue the game but a quick drop into 'Training' revealed that the issue was confined to the on-line game. The Spit handled flawlessy with my usual setting. 'Hurricane' experienced exactly the same problem and had to reduce his sensitivity in order to maintain acceptable handling during the 'laggy' games. It seems that 'lag' also affects the handling......
