I'm assuming you read a "126" on the hydrometer, which is actually 1.126 rather than 1.26. It's really hard to take an accurate gravity after you add fruit. Take it before the fruit addition next time. I'd bet the article is closer.
A quick ballpark estimate. Sugar content varies a bit in honey, but 36 points per pound is a reasonable estimate.
22.5 lbs honey x 36 points/lb = 810 points
strawberries are about 5% sugar, so 17.5 lbs would contain .875 lbs of sugar
.875 x 45 points/lb of sugar = 40 points
810 + 40 = 850 total points in five gallons
850 / 5 gallons = 170 points per gallon or an approx OG of 1.170
This is a BIG melomel. ABV will be high if the yeast holds up.
