Well, the ABV if those readings are right is 8%.
(OG-FG) x 131 = approx ABV% is the correct formula.
I don't know how much honey 3 cups is (weighing items is far more accurate, so I weigh honey), but I'd guess that it'd be 2 pounds or so.
2 pounds of honey in a gallon of liquid would give you an OG of about 1.070 or so. If you had more sugar than that, of course it would be higher. I just wonder how well the batch was mixed.
It sounds like it fermented pretty fast, to get to 1.026 in 48 hours. That's not out of the realm of possibility, but it seems like you'd get bottle bombs and not just bottles that are "hard", though!
Something here just doesn't add up, and I'd blame an inaccurate SG reading in one or both readings.
