Rather than using terms like "Look Guy" ... (pull your head in by the way ). I tactfully suggest you read the posts carefully before flying of on a tangent and throwing your two bobs worth in.

So far in the Spit and Hurris speed test threads the 3 tangents you have gone off on are:

1. Suggested using the dry Adiabatic lapse rates instead of the ISA Lapse rate.
2. Asked about Vy speed in a level speed test.
3. Suggested that airfield field elevations varied with pressure.

I clearly stated in all the posts no adjustments were made to standard conditions the data is as it is. I also indicated in the Spit test post the FTH quoted was as stated the Altitude at which during the Speed run I first noticed the Boost drooping off. So in the test case was the Rammed FTH. As I indicated in the Spit test no attempt at converting to a standard atmosphere was made ... and I invited anyone who wanted to to go for it !
