LTFTs, RPMs & MPHs

[ALK]

07 A6 C6, Predator 7194, 93 octane tune. Since LTFTs should be recorded at a certain RPM say 2000 RPMs which in my case is 55 MPH in 4th gear or 35 MPH in 3rd gear. Is it ok to log one time at 55 MPH in 4th gear and then compare adjustments made to those LTFTs with LTFTs taken at 35 MPH in 3rd gear as long as 2000 RPMs are held? Its the RPMs that count, right? Or am I mixing apples and oranges?

rpm is more important than mph. drive at whatever speed it takes to get 2000ish rpm, remember don't make your self a rolling roadblock

cruise on the highway.... keep the rpms between 1800-2000....
