How is the air speed measured for different air craft ?

eg The Japanese tested their air craft with standard fuels and reported that the frank did 387 mph , the US tested the same plane and reported 426mph as the maximum though to test the maximum ( ihave mixed reports on this using a 100 octane and a 140 octane). My question is did the US used standard fuel for maximum speed test and do the primary sources pass on this information ? Now the Japanese used 91-94 Octane how can a plane using 6% (assuming 100/130) or 20%( assuming the post war 115/140) more octane rating shoot from 387 to 426mph. Im inclined to think there were just different ways of measureing maximum speed.

Also did the US really have 140-150 Octane rating fuels or did they just used the enriched value eg 100/130 teh Germans call 100 and the common post war 115/145 most people termed 115 maybe some authors termed 145. The reason is that i cant see any ( non Hydrogent based) fuel being 140-150 .

Lastly there was a German synthetic fuel coal fuel cracking plant in Manchuria why could this not produce 100 Octane like the Germans did (or did it but the quantity was too low and it was just blended) ?

Also do both use ground speed or air speed ?

I have been in a 747 doing 1080 km/h .. but that was the ground speed.
