Looks like an excuse for the track to turn on the insides to lead to the claim of over 4 km. Probably no worse than the back to back 190* turns of Dunnville.
I think “Curve Grande” @ Dunville would be good if ran in reverse. Then you carry speed going into then brake to load the front. The configuration that is normally run there you are pretty much accelerating the whole time and loading the rear of the car and pushing.
For Shannonville I would either run the “Pro” or “Fast” configurations…(if it were up to me)
