The best way to bring it back is to try and organize the testing again.
You here a lot of things behind the scenes about the current testing being bias or manipulated.
Bringing back the controlled testing project would be beneficial to everyone.
I believe @buck1973 and @Racepicks were discussing another round of testing at some point but the threads didn't gain any traction then.
For some reason many appear fine with the Sponsors doing their own testing now??
