Here is the drift scoring calculation from insim "Drive_LFSS"
Take into considaration:
Time,
Speed,
CarTraj -> CarAngle,
TrackTraj->CarTraj,
CarAnlge->TrackTraj,
Counter Correction to keep Drifting,
Stay on track,
LostControl,
360 and more,

Here is the LostControl thing, make a difference between a drift and a lost control , really depend on the Track Direction
double tracjectoryDiff = GetAngleDiff(trackOrientation,car.GetTrajectory());
car.SendTrajDisplay(GetTrajectoryDisplay(tracjectoryDiff));
double orientationDiff = GetAngleDiff(trackOrientation, car.GetOrientation());
car.SendOriDisplay( GetOrientationDisplay(orientationDiff) );
double perpenDist = GetPerpendicularDist(car.GetPosX(), car.GetPosY(), node.centreX, node.centreY, node.centreX + node.dirX, node.centreY + node.dirY);
car.SendPathDisplay(GetPathSideDisplay(node.driveLeft,node.driveRight, perpenDist,car));
if (car.GetSpeedMs() > 0.1 && (Math.Abs(tracjectoryDiff) > 16 && Math.Abs(orientationDiff) > 19))
lostControl = true;
else if (car.GetSpeedMs() > 0.1 && Math.Abs(orientationDiff) > 19)
drift = true;
Scoring happen at a static Tick time , me i use 150ms , so each 150ms i calculate your drift score until i detect your no more into a drift or you completely lost control.
P.S. a sucess 360 into a drift can be real good if you keep on the Track.
All this code is very old and was made before i complete Map System, so it can be a lot better.
Let say i don't have motivation or help needed to update that code , but hope gave you idea to build your own or anyone else
bye bye!
