I look at the wake . . . if water is coming cleanly off the bottom and flat for several feet behind the transom and water from around the sides is converging into sort of a rooster tail behind that, and you're at a point where you can rapidly pick up speed with additional power, I'd say you're on plane, even though the running angle continues to flatten out as you pick up speed. The Boating Magazine test on an I/O Seafari showed running angle continued to drop up to about 25 mph. It's optimum mpg was at 19 mph, where the running angle was relatively high, but it evidently didn't have as much hull in the water at that point!
