It would be interesting to see some of the driving lines GPLRA reveals the WR challengers have made from Tarzan to Jan de Wilker.
My preference seems to be exiting Tarzan on the inside and staying to the right up to the crest at the bend to the left, almost in a straight line from entry before the crest to entry to Gerlacht, crossing over to the left side to clip the bend at the crest, so after the crest the car is on the outside for entry to Gerlacht.
If a driver rather goes to the outside exiting Tarzan and does not cross over to the right before the crest, after the crest they will likely be on the inside approaching Gerlacht, forcing them to slow before climbing the little rise that precedes the short straight down to Hugenholtz.
In contrast, landing on the left side of the track after cresting at the bend places the car ready to take the maximum arc thru Gerlacht, possibly with less incline to overcome, and the option at exit of choosing any entry point to Hugenholtz.
Once there, Taruffi's suggested line offers the opportunity to apply constant radius around the extreme track camber close on the inside thru the turn...which actually seems a good enough line that takes less time in the turn even tho the car slows to 45 or so MPH.
The problem is the hill that follows. So far glimpsing a few times at the speedo up near its crest reveals a rough guess that taking Taruffi's line is about 5-10mph slower at that point than my erratic late wide apex guess of the fastest average exit speed thru the turn.
Which line is faster overall? I have no idea.
Lately been running consistent 1:27s in the 67LotusF1 with 14-lap fuel load down to a few 1:25s when the car lightens up, (just saying so you know, for me its all about style not being fast...because I'm not, plus daydreaming a lot).
Edit: Well, hm...now uncertain exactly where Gerlach is and how to spell it. Going by the GPL Program Menu track map comments above might be confusing, or the track map is, (which I figure its not).
