Actually I have read that entire thread since watermelonpunch posted the link. The thread looked abandoned and most of the discussion tended to be pretty circular on both sides.
Those like myself that were hoping that PP was actually a semi accurate indication of vehicle performance regardless of vehicle type/class
That's the point. What anybody hoped the PP system could do,
it doesn't. We can complain, but as it stands, it's best to just accept that.
I think what people really want is a system that can hands down tell you what car is going to do better than what other car.
Well, that's pretty impossible. So many factors go into what makes a car better... and then something as simple as a transmission setting can make the difference on one track as opposed to another...
The game's just a lot more complicated than to be able to just give you a simple system to tell you what car YOU can drive best. Like a difficulty setting or something. LOL
And yeah, what chuyler1 says might
seem preposterous. But I happen to know that chuyler1 is just experienced or talented or quick-reflexed enough to take some cars that some people might think are "losers", and actually win against maybe a mechanically advantaged car with a newer player driving it, or someone not as clever.
And someone who's just REALLY good, will just not need much mechanical advantage to blow away the competition.
Expecting some in-game number to tell you something definitive is an exercise in futility, simply because of how many variables come into play with inherent car handling, power, torque, hp, speed, transmission, suspension tuning, and driver skill/experience.
Add into that someone who knows a particular track very well, or not much.
There's no "secret" that's going to apply to everyone all the time with every car on every track. Disillusionment is hard, but once you accept this fact, it gets a lot easier to come up with a strategy for yourself.
Forget about what PP means... and just take what you got & work with it. Just use it as a restriction starting point, and go from there.
