Hmm - for long tracks like Spa I could raise the start value a bit. But on shorter circuits with the gain settings we have you'll be on near enough full grip in 10-15 laps.
The settings that we and most other leagues run are utterly unrealistic though, The closest thing to a 'fast' track I've ever been on from the start of a day was Coombe, a couple of weeks after they resurfaced. Prior to that a fresh day after rain would be more like 60 or 70% in AC land
This is a historic endurance series though - You'll be looking after your car as much as you will be racing regardless of grip levels (both Porsches and the Fez need the gearbox looked after, the 908 also has no limiter
).
Approaching it like a sprint race or fighting for every inch from the get go will not give a good result.
