If you say so. Of course, pulling my 5th wheel
I have ranged from 8mpg to 16mpg depending on the wind. While there are some differences from current, that seems pretty substantial. I still generally assume around 12mpg and leave a decent margin for error.
Of course most people I know have no clue how many gallons they are from their destination
(not that even makes sense). They do typically know how many miles. People talking in gal/hr are indirectly making the MPG calculation based on an assume cruising speed. In either case wind and current and sea state must be accounted for.
If gal/hr makes you happy, go for it but I stand by my original point that MPG makes perfectly good sense.
