I didn't expect to win that much advantage in sector 2 compared to sector 1. I consider sector 1 the hardest, then sector 2 is only one corner (and the rest is flat-out) and sector 3 is just another corner. Many guys are running good T1's and then lose some tenths at T2. Try to focus on the exit of the hairpin at the end of the tunnel, do this corner slowly so that you can do the next left-hander flat-out, then keep accelerating through the S.
