Well, to create a good turn let's say 90 degrees to the right, I need to place a least 4 points to move the car thrue - and set the timevalue right:
1. end of straight start of deceleration
2. slow point apex
3. end of turn start of acceleration
4. controlled acceleration beginning the straight
a chicane should be a lot more travelpoints and I cheat a bit sloppy, maybe I will tweak it better in the chicane and acceleration aspect, but, as things look now - I almost only have the possibility to get the lap time for the winner correct...
Only if a save game included a last lap telemetry performance data then things would be exact. Now, I need to do a telemetry performance file on my own (and for germany I only can make 1m46sec) then I give or take to fit Brezza's 1m40sec and the others 1m 44sec (I think both Lyon and Dags made an error on the last lap - I guess where).
The final dislay, with the winner reaching the finish line and the others freezed at their place on the track is rough, sadly.
