Also at Cadwell Woodlands, you should squeeze in about 10 or so laps in practice/qualifying, so there isn't such a need to try too hard too soon. 3-4 laps to warm up, and then 6 laps at your quick pace.
And remember, you don't win anything for breaking lap records in qualifying (apart from pole).
Better to ride at 90-95% and stay onboard, than go flat out and go home before it all starts!!
