Ok, I'm not totally sure, but doing chassis repair already after only 200km seems to already have some effect to the cars handling (makes it bit stiffer) at least I'm pretty sure that deterioration is noticable before 500km when the deterioration light goes on...
I'm mainly spending my time grinding in TT's and seems to me like I have done many of my best times within 150-200km from last chassis repair... This could be a placebo effect no doupt, but I can't seem to be able to convince myself that this would only be in my own head... I could be wrong, I have been once before, but that was an accident 
Thoughts?
EDIT: Ok, just to elaborate my though on this, in many tracks there's a huge variation on corners and usually in slower corners it helps if the car is a tad more looser so you get the rotation, when in really fast corner even a tad stiffer car can give more consistent results there fore giving a tad better lap times. So IF there's a minor change in rigidity under 500km it's little and very insignificant (and I'm not quite sure if it's happening) but always when my body rigidity light has already turned yellow, the car has become really sloppy and doing the restoration gives the car better "posture" so you can handle it easier, so yeah, I would say do the rigidity restoration at least after 500 km, car behaves better, at least IMO.
