Tl;dr Many gels you buy (manufacturer dependent) over advertise both the carbohydrate and Kj content of their products, not just Spring Energy.
I suppose this should be a surprise to nobody (if you only legally need to be within a %, why not be at the lower limit IOT save money).
This seems like a good case for making your own mix. The fact that it’s cheaper as well is just a bonus to it also being more accurate.

Except Spring Energy (maybe they should rebrand as Spring Water) and Näak, they seem pretty close. Huma is low on energy but not carbs, seems odd. Maurten is dead on on carbs and slightly over on energy.
