The math isn't off and you aren't retarded. I could definitely explain this a bit better, and I've gone back and forth on exactly how this should work.
Because this is a ranked choice poll, the percentage number is your group's preference. You could rank an option as a first, second, all the way to n - or not even rank it at all (deleting it while ranking with the red X). If everyone ranked an option 1st, then that option has 100% preference. The further you get from everyone ranking the option 1st, the further from 100% preference it is.
The preferences are not cumulative, in other words. Instead, each preference percentage is specific to that one option.
