I looked at this properly now.
Glickenhaus has the theoretical fastest lap too. Other class theoretical poles are shown too.
There is much to make this theoretical! These times are just the sum of the best sectors of each car over both sessions. It could be different times of day, different set-ups or different drivers.
Shout out to #92 (Kevin ESTRE), #388 (Jeroen BLEEKEMOLEN) and #69 (Robert RENAUER) who's theoretical fastest was the actual fastest for that car.
