.095% slip- sound right?

[buzzaro]

Thats what I got when I crunched the numbers 68.5 @5k rpm w/ 24p prop & 1.5 gears. Does this sound right? It sounds a little low to me but I am no expert.

Thats the right calculation. Did the speed come from GPS, or speedo? Seems ultra efficient.

That number is incorrect. 9.5% is a more likely reading.

Using the numbers you provided, you are at 10% slip which is a very normal reading.
