Here's the full video (with sound) from that session
http://www.youtube.com/watch?v=i9Lm-bUDaPIthe slide happened around the 13:13 mark. All I remember thinking was "well there goes my damage deposit"

i think i had run over a painted line which had less grip as it was wet (chicanes always feel more slippery to me as it is), juding from the engine noise i was powering it on slightly as i came around, and possible chopped the throttle or clutched in. I guess the best thing to have done would be to clutch in and let the tyre regain traction.
I was running a set of racing wets, so luckily they had a lot of grip, I'm not sure if I would have stayed on with a normal set of tyres.
I know now my body position was wrong (I'm still a novice), I had an instructor follow me later on and he noted that I should be leaning my upper body off more, as I was keeping it centred. I also need to work on my downchanges (and not being afraid of going too fast on the straights). Was watching the Simon Crafar Motovudu video that I got for xmas, and that had a lot of useful info in it too, such as getting lower body in the correct position for the corner while the bike is upright, so as not to upset the bike.
Can't wait to get back out and do some more track days
