data can be skewed if there isnt a consistent and constant procedure that is followed.

Consistency is the 50-100 mph speed range. Counting the timing via the inaccurate speedometer and a video will skew data accuracy anyway.

I would say just do it as fast as you can. Try out different methods if you want. Either way it will be a poor mans result without proper timing equipment.

If you're comparing how fast the vehicle is, why would you want to deliberately start that test at such low RPMs that are way below the powerband? 4th gear makes absolutely no sense IMO. At least in 3rd gear I believe you would be around 4K RPMs at 50 mph.

**note** I am speaking to NA vehicles here, not FI.

I know the 2500 RPM is below our power band more in the 3's but these where for tuning purposes and was just stat the MPH and gear I was using. I'll do 3rd gear is fine with me, The 99 MPH is more like 105 or so, my speedo is most likely wrong with my 20's still on the car
