Please don't say that there isn't enough time to test that layout. In real life there is only 2 hrs practise session for an ELMS race and even in Le Mans there is only 12hrs (which is actually not long at alĺgiven the fact you have one car, 3 drivers, 50% rain, 50% night and 7-8red flag) of testing before the race, starting on wednesday. That chicane will not change drastically setups anyway...and there is only one corner to learn.
Expecially from teams below top10 it might be difficult to learn it properly, without any mistakes...
