"it might be as little as 4 tablespoons of water per gallon" I would say if you only need 4 tablespoons to absorb all alcohol in one gallon of fuel, you did not have enough alcohol in the fuel to be worried about.
Think this: The suggested 10% mix of alcohol will be 100 ml for every Liter, that is roughly 400ml for one Gallon of fuel. 400 ml is almost a pint! 1 pint (US) = 32 tablespoon (US), but to be correct, let's go with the real numbers 400 milliliter = 27.051218161 tablespoon (US) 27 Tablespoons for a 10% alcohol mix! A 5 % mix of alcohol makes for at least 13 Tablespoons/Gallon. By the way, I would not recommend adding water to the fuel at any circumstances. Water goes in solution with fuel also, not only with alcohol. Also alcohol likes to stay in solution with gasoline AND water. We used this feature to clean out water in fuel tanks by luring it into solution with alcohol, that will be in solution with gasoline. Makes for nice dry tanks in cars and motorcycles. The watery, alcohol saturated fuel would not clog up the jets in the carburetors as water alone would do (hereby stopping the fuel flow) and the stuff would just burn normally with a lightly reduced octane number and less resulting power. I noticed that you can't do that in our Ercoupes. Water saturation will be filtered out by the gascolator. I had ones a pretty much water saturated 100LL/Mogas mix in my Coupe that would not show any evidence of water when draining the fuel sumps. Yet the gascolator was filtering out the water in flight to an extend that it was filled up to the neck with water after 2-3 hours of flight. Since then I am healed. No more experiments with ethanol enriched gasoline. And luckily, I can still use Mogas in Germany, since the latest attempt of introducing a 1=% ethanol mix has been stopped. Latest price at the pump: € 1.40 /liter or 5.29 Euros/Gallon. Which is roughly $8.21/Gallon with today's exchange rate - This is for Mogas from the pump Ladies and Gentlemen.

Physics are the same regardless of scale. As long as you add sufficient water you will cause the alcohol to be absorbed by the water. I think it might be as little as 4 tablespoons of water per gallon. The test works the same as with a larger amount.
