Remember too that if there is fuel in the fill hose that there is fuel in the vent hose. Often times the vent hose isn't inspected or replaced at the same periodicity.
Main Sailor did some experimenting with fuel tanks and condensation. FWIW he did not find that any more condensation accumulated in a partial tank. As such I take a different approach to fueling my boat. Typically I won't use the entire 40 gallon capacity of my tank in a single year. So unless I'm going on a long trip I only fuel up with 10 to 15 gallons. I try to plan it so that I can fill via jerry cans through a filter funnel. At roughly 1 gallon per hour I know that I'm good for 10+ hours at full load. It only takes about 30 minutes to motor out and motor in so I get a minimum of 10 day sails between fill ups and that is very conservative. By filling in this manner my fuel always stays fresh and any minor contaminants will get diluted by the next fill up.
