So we can agree that it is possible to ascertain drag reduction from throttle stop testing?
That is of course assuming the following:
Accessory load is the same (no-air con, no extra lights, heating, etc.)
Tests are done back to back multiple times on the same day to average out any wind changes.
The vehicle is appropriately warmed
The fuel is the same
Whether it is safe to block your throttle, or accurate enough to measure a 1% or 0.5% drag reductions is yet to be decided/ascertained, I will not argue for or against either of those.
