Dennis tracks

[Dennis]

I tried to make the best possibble laps (lap parts), but after I was ready, I was surprised, that some AIs were already with full tanks faster, than the LP time. So I changed the RELS to 98, to be competitive.

The AIs are really tough. On other tracks I know where the AIs have their weaks, where I can overtake them, but here I'm racing against "myself", so overtaking is really difficult (at least for me).

I think I've found the reason, why the AIs are too fast. I made some race laps, and the AIs looked OK on the straights and in fast corners, but in slow corners they passed me everytime with an unbelievable speed. I watched the replays and they were in fact too fast, and it didn't look realistic.
I had an idea where the problem can be, so I tried it, and it works.
It seems, there is a bug in lpedit at the speed calculation.
As we make a TXT file from a replay with trafo20, it extracts the angular speed of the car in the corners, and it calculates a virtual radial speed at the center line of the track. This is higher, if we drive on the inside line than on the outside line at the same speed. But it seems, that icr2 interpretes the speed value in the LP files as radial speed on the racing line, and that's the problem.
My solution is: recalculating of the speed values in every corner with Excel before making any further edits with edit45.
The formula:
v=w*(r-dir*p)/r
where
v: radial speed at the racing line, needed for the LP file
w: speed data made by trafo20
r: corner radius in feet
dir: direction of the corner -1 for right corner +1 for left corner
p: position data made by trafo20

Now I could change the RELS back to 100, and the AIs are much more predictable. They don't attack and pass me in every corner (just in every second corner :-)).
