According to the regulations
http://www.old-drivers-spirit.fr/fichiers/2010/reglement_champ.html (Chapter J.2, page 12), you were to offen "off track" (outside the white lines) (shortcuts and/or using outside the track before/after a corner)
It's tolerated to go out of the track 5 times/hour (problems like braking to late or similar don't count) with 2 wheels.
You aren't allowed to go out of the track with 4 wheels (problems like braking to late or similar don't count).
In you case, the following "shortcuts/our of track were counted" (I don't know if it was with 2 or 4 wheels):
L1: 1.04-1.11, L2: 1.01, L3: 1.02-1.25, L5: 1.26, L7: 1.26, L8: 1.03, L10: 1.26 ...
So, the 5 tolerated "cuts" were over a long time before Lap 10.
Yes, the corresponding penalty is to start from pits at your next race

I agree with you, it's a Shelby track. But I will not use the Daytona (but I knwo who will use it

). Peharps a Cobra, or Vette or GT350, I don't know, I will test them (and the track) probably tomorrow evening.
