As someone else suggested on here, start by going the speed limit. Then try going 5-10mph BELOW the speed limit. 30-40mph will more than likely yield the best mpg in 5th gear.
Technique will be the most important thing besides speed. Pay close attention to your acceleration and slowing down habits.

Agree on the main points. I'd just add 2 things:
1) I don't think the wind is much of a factor until you get into the range of freeway speeds. Once you get there it starts to make a difference, and once you really get going fast, it makes a BIG difference.
2) Can you actually be in 5th gear @30-40 mph in the AT fit, (which is much taller geared than the MT)? The MT doesn't like 5th below about 40 mph.....
