Your argument is understood but there is a significant difference from com8 Nürburgring to the versions recreated with the scan data. How bumps are implemented or reproduced is not the data's fault. Also, there is significant difference from Team ORSM's Bathurst to the ISI-sponsored Bathurst (same track as in NFS Shift 2/pCARS), and scan data. The modding group release is much closer to the iRacing version. Resurfacing will indeed alter the accuracy of bumps but not camber or elevations, so the argument of "resurfaced such and such since the scan means it's no longer accurate" is a bit of a stretch since other non-data based builds may feature grip that isn't accurate either, or also lack bumps.
