That's probably true, but the problem is GPL works with distance tow, not with differences in drag, or power...in real life, the bigger hole that is punched in the air, the bigger the tow. Also less power will add to the tow effect. (see NASCAR Tona/Dega for example)
I guess the modmakers tried to compensate with more distance to allow for more tow effect, but IMO they overdid it on most mods, while it's too little with original 67s...
It does not, it does, it does, it does not, and it does not respectively :p .
I'm a student mechanical engineer, and people aiding in the development of the new slipstream model are professors of universities, have flown fighter jets or were professional cyclers. We used our background to validate the lap-by-lap data we had of the 1966 Reims race, where Brabham was slipstreaming Bandini.
The 1965 cars have the exact same slipstream models as all the other mods. Because they have a slower top speed, tow is reduced. As you might know, slipstream is related to speed with a square formula, which means slipstream gets four times as strong when speeds are twice as high. But as said before, the physics of the 1965 mod and any other mod is all the same.
Compared to original 1967 Papyrus model, the strength of the tow is reduced. The length of the tow is increased.
The 1967 originals have the drag of the cars set too low, so they run the same laptimes at Monza compared to real life without the aid of tow.
I've had this discussion many times, we tested the new slipstream model extensively with the 1966 mod, until our data matched the Reims data. After it's implementation, we finally got the 1969 Monza style races were were missing out on previously. I know the draft can feel a bit strong, but aero is a thing that is difficult to comprehend sometimes. I mean, have you ever seen that Antonov freight plane fly? It weighs 640 tonnes and takes off at only twice the speed of what we were doing at Le Mans last night.
A Dutch cyclist holds the record for highest speed on flat land (no downhill). He got up to 167 mph on his own power slipstreaming a dragster fitted with a special windshield to aid in drafting. Drafting is used in track cycling where a guy on a moped brings the cyclist up to speed.
