Below is a table showing the mileage I received during the trip. I can't find the old data, so I don't know if this is better or worse. My sense is that the prop repitch worked, and that these stats are at least 10% ahead of what I had.
|rpm||Eng Load||Eng Load||GPH||GPH||GPH||Speed||Speed||Gallon||20% reserve|
|– The difference between indicated speed and True speed is Current. I was being pushed by a .9 knot current|
|– Range is computed by assuming fuel capacity of 3,000 gallons, with a 20% reserve (2,400 gallons useable)|
I just discovered some old stats, from a year ago. Below is a chart, comparing my NMPG (nautical miles per gallon) before repitching the props, to after repitching the props.
Neither set of data was captured perfectly, so I'm trying to control enthusiasm, but the indication is certainly that I've picked up approximately 20% in range at the RPMs I usually cruise at (around 1375 rpm).
