Ran the GAP tool on the rear diff. Anyone explain a little more on what the values are actually?

Percentage Travel remaining on clutch - Mine was always at 80%. I assume this means that the clutch is engaged at 20%? And that there is 80% more clutch engagement available as needed? On the drive home, this was a steady 80%.

Slip speed - I tend to think this might be the difference between outputs? Mine was always below 1.0. It would fluctuate a lot, biggest peak was 0.24.
