to talk to this point of 3rd vs. 4th gear, I cannot tell the difference when looking at the charts weather a dyno pull is 3rd gear or 4th gear unless you change the charts parameters to actual speed MPH, and not engine speed RPM.

Otherwise, you could end up laying 3rd gear runs over 4th gear runs and not know that its not apples to apples, in the RPM band, it looks like apple to apples.
