Ahh I mistake I thought it was. Is your version more accurate than theirs or is theirs very close to reality?
I checked some videos and it does seem that the down hill section is indeed steep and very similar to theirs (there is a comparison video) and I do enjoy the up hill and down hill nature of that track.
This version is absolutely remarkable for a mod, but it does feel a little latter than theirs, but that's not to say theirs is right I suppose
In September last year the Environment Agency made LIDAR data available for much of the UK. I was curious to see how close I'd got, considering I'd started from nothing more than this:
Here's a comparison of mine (red) against it corrected with the LIDAR (blue):
It's unfortunate that the area containing Redgate and the top half of the Craner Curves is missing from the scan, but given the rest is so close I'm pretty confident the rest won't be not far off. There's certainly no scope for making the first part of the Craner Curves any steeper.
It's possible that pCars version might just 'feel' different due to FoV settings etc. Otherwise it's probably just wrong.
