I realize it's not the same car. But I doubt there's anything special about your Camry that makes it not follow the pattern of all other cars:

Lowest practical speed in top gear = best fuel economy.

The exception may be in hills: a higher average speed may help if it permits you to stay in top gear on ascents while bleeding speed (DWL) while avoiding downshifts.

You're doing a good job of investigating. Keep it up!
