Well, I´ve seen two laps on the live timing, in the first I´ve seen you cut the chicane, not stop and thus catching up to S.A.M. just to do the same thing the next lap again (this time you stopped with the DNF following)..
Before that first lap I´ve watched you already had the fastest lap of the race by a whole second (and even 1.6sec faster than the race leader), so the first time I´ve seen it wasn´t the first time you've done it.
So you did it at minimum 3 times in the races, and you already did it on Saturday based on your laptimes on Saturday being 2sec faster than yesterday's fastest lap time of the race from you. You already knew you could gain lots of time there from testing it Saturday...
Cutting the course like this is just not acceptable and if you want to do it, then the race servers aren´t the right place for it. Nobody will be upset if you leave out the chicane in an offline session...
