Greg, I finally watched your video, great work. As we have discussed my 2000 410 doesn't get the economy that yours does. After a 300 mile trip last summer I averaged about .64 mpg, now that did include getting on plane, rough weather on Lake Erie etc. but clearly not as good as what you get. What size props are on your 1999? Mine are 4 blade 21x21.
Attached is the graph I put together from my Fox Marine Gateways a few years ago. The big gap in the data is the transition from cruise to on plane. Some of the data is interpolated but in general just as you described the faster you go you see a drop off in MPG:

This sounds pretty decent if you were running in rough water with plenty of tab? That's exactly what I got this year in calm water, running too fast (22-23kts) with 500lbs of dinghy on the back...
