that's an interesting question.
there's sort of a usefulness threshold, and then there's a "can calculate insulin" threshold.
I think a LOT of people could benefit from plain high, medium, low with the understanding that you wouldn't make insulin decision based on it.
I have a friend who tried one of the invasive continuous glucose monitors and finding out which common foods spiked their blood sugar the most and the least was useful.
