I am wondering about the same thing. I am not too sure what the Amp reading is telling me. I have a 5.5T and 6.5T. The 5.5T on the Analyzer is reporting higher Kv than the 6.5T, which is expected. But the 5.5T is somehow using 8amp (lower) vs the 6.5T's 9A. On the track, the 5.5T definitely using a lot more than 6.5T with shorter run time...
