There is a standard procedure outlined by Guinness World Records to validate a land speed record. The vehicle must drive the predetermined course, turn around, and drive back the opposite way within one hour. This is to negate any discrepancy there may be in the course or conditions. Top speeds from each run are then averaged to obtain the official speed. This method has been used for decades as the benchmark for land speed record attempts.

Dewetron, a company known for performance testing of missile, train, aerospace, and automotive capabilities will accurately monitor and measure the speed of the Ultimate Aero for the record run. Dewetron�s equipment is so precise that Guinness World Records approved their systems as a replacement for the standard 1,000m laser traps. Dewetron utilizes 4-12 satellites and numerous onboard sensors to track a vehicle�s speed.
