I do try to top off the tank until it won't hold any more, thinking that's the only way I can be sure it's the same each time. Is this somehow wasting gas (burning extra out of the carben cannister & running rich, or something).?

Your short trip mileage will be hard to beat compared to your tank mileage in the first few miles because you have only been running a few minutes on the tank, vs many hours. I have run over 20 hours on a tank (1200 minutes).
