Nothing wrong with 5 gph if it works for you. Perhaps you even run at less than 65% power?
But, as a 'fright' instructor, you might not want to get called up on the FAA red carpet to answer why your student ran out of gas. The FAA can be a terribly unforgiving bunch....... Especially, if you make $$$$$$ with a license. These doods carry a BIG stick. I think Steve has the right idea at 6 gph for his fledgling baby birds. Erring on the side of caution is what needs to be demonstrated. Call it CYA, if nothing else. BTW... My 85 hp Coupe uses more than 5 gph since I use 75% power and run slightly rich PLUS the climb to altitude fuel burn. It's a TLC treatment my exhaust valves seem to enjoy. I won't mention if Marvel Mystery Oil is in the gas. <g> BTW... Just fer grins: Flying an 0-200 Coupe at 63.75% power and a C-85 at 75%, yield similar performance numbers. Figures can lie and liars can figure, but hopefully NOT much in this case.
