then you’re going to have to do the math

Why? It’s listed in both, so you know a spray is close to zero. If you’re using more than a couple or few sprays, you’re doing it wrong, so what’s even a few sprays? 5 calories?

Your measuring inaccuracy on other ingredients is going to be WILDLY more than the calories from the oil. Baking and spray the baking sheet? When you measured your flour, did you get it to the nearest TENTH of a gram? Because a gram of flour is like 3.5 calories, so if you were off by a single gram - or your scale doesn’t even show decigrams, then the rounding error is likely more calories than the oil you use that adds to each ‘serving’ of the thing you’re making.

So this is extremely unimportant.
