is it my imagination or has SL managed to make wipeout distort time..

example i have noticed mysef are...

started on Ap forward in first got good start on first straight after bend i go a bit to far to left on top of the wall but still flying top speed then suddenly everyone was 4 seconds ahead even though i never crashed or lost speed..??

or on ubermall i did turbo of hill into br but clipped top of window...i drop to floor then br activated ..to me it seamed like 0.5 seconds lost but in game i lost at least 5 seconds..

their are many other example of time in game not matching real time...

have i been playing wipeout too long and have gone insane or have others noticed wierd crap on a quantum level
