For shits and giggles I tried it with 32 tracks and got 32% and again with 64 tracks 47% and when I duplicated the 8 tracks the last time i did it during playback.
Went up to 96 tracks peaked at 66% hoovered around 64% And I did pretty much all of this without stopping. It does say at the top live 6-7 though thats the right test correct?
