I did actually record my session so I've uploaded it below, lost at least 2 tenths at T3 and 4 from braking slightly too late and losing the rear on exit (going off my S1 times on later laps), my sector 2 was pretty good as I struggled to match it on later laps and the chicane I think I could've gone slightly quicker

How I was going about the lap was: The lap starts at the chicane so firstly make sure you get a good exit out of there, T1 is flat, just turn in when you get to the grass on the left.
For T3 I was using the first set of dashed lines as a braking reference, as you pass them, brake, drop down to 5th, throw the car in when you get to the kerb on the left and floor it out.
For T5 the start of the kerb was the brake reference and once again dropping down to 5th and throwing it in.
For T6 you can use the electrical post on the right as a reference and you want to exit T7 in 4th gear to avoid wheelspin
For T10 brake just before the 2nd set of dashed lines, drop to 3rd for the first apex then upshift to 4th for the exit
Though saying that it was mostly just chucking it in and hoping the kerbs didn't spit me out.
