loll. There are 2 possibilities: 1. they time lap times in different days and different conditions; THEN there might be a remote chance they did not sandbag the 488 pista. 2. they tested the same day in the same conditions, THEN this proves they pathetically sandbagged 488 pista.
Your ridicolous claim "they say they were fair, so they were fair" is totally independent of the lap times they got. Had they posted 1.27min, 1.45 or 3 minutes with 488 pista, your claim would still hold, since the magazine editors say there were fair.
It comes to mind the fair f12 laptime at laguna seca by Pobst, or the fair scuderia vs zr1 sportauto's test, with a corvette cr6-gt1 driver, when they tried to do 11 laps with the zr1 and only 6 with scuderia...
