My delta dash results showed 300/310, the rollers on Saturday showed 280/260..
I trust the rollers myself after using them since day 1, hosting several RR events and seeing loads of cars mapped on them.
Ask GRD how well his cars produce figures on them, he is in the business where his customers would like the quoted figures for the work done.
As for quoting Bob, he has only ever used PE for his R&D.
These RR arguments have been going on for years..
