Help reading different DYNOSHEET for ZL1

Can someone go over the Ratio TCF and Gain statistics at the bottom? Any particular reason the gain shows 0.1 and then 0? Sorry if its a noob question just different from previous dynos. Thanks guys

A guess but the gain is likely an adjustment on the dyno as it relates to sensitivity....and not about gains in performance? You know how sometimes you see a dyno sheet with a very squiggly line? That is likely because the gain is turned up too high. Or a squirrely RPM signal.
And after a bit of research, TCF stands for "Transmission correction factor". If the operator knew exactly what the drivetrain loss was then by adjusting this he could get an estimate of power at the engine. ie....if there is a 15% drivetrain loss then he could set the TCF to 1.15 and it would basically increase the numbers by 15% and you would get an idea of power at the engine. I would assume almost everyone sets TCF to 1.00 to get a reading at the wheels.
