I was interested in the METHOD for determining the portion of insects. And this answer cannot be measured in grams.
I am a programmer and, if you understand me, I needed an algorithm.
I'm also, and I can totally this thinking. Often also "thumb rules" drive me nuts
Like "a plate full": plates can have different sizes and you can pile to different heights... Or T-shirt sizes by age
I personally keep it not strictly 80:20 but agreed for myself to see this as an approx. rule. There are so many variables: Dragon has eaten less veggies one day - immediately reduce insects the next? (I don't do so.) Change diet on days he's more active vs. not? (No. I put it in, he selects.)
I try to keep it "over the long run" at what looks approximately 80:20. As also the 80:20 has not been exactly defined scientifically, so really hyper-precisely measures AFAIK, and so I don't have to worry whether I have to use the lab scale or whether I count by volume, weight and also calories if not doing extreme cases (like fluffing up small-leave greens or only offering food with a relatively high density like pumpkin or nutrition-poor like lettuce).
And for a "normal portion" I'm also not doing like "I feed a small specified-size bowl full each day precisely three times", but whatever he eats and his look stays within a normal range and is not totally off (which would be like: 1 bug a week, or 20 superworms a day). When Taco eats from live plants, I can't even specify how much it was (I would have to dig it up and weigh it, taking into account water in the soil... no
) - but I see he'd not eaten many bugs, he poops, plant gradually gets smaller, I see him eating that plant, so...
I'd be very very much the "algorithm type" also with that, but I've agreed for myself on that I don't have to keep it exact and the 80:20 is more to show what should be approximately fed to not end up with "all worms buffet" or on the other hand "eats like a rabbit". Same as for myself, which food should be more in the "often" or in the "rarely, sometimes" category without having to specify exactly whether once or twice a month from "rarely" is too often (daily for sure is). That's not like the salinity of a sea water aquarium where I have to know precisely what is the method on how to define and measure the proportions not go by "throw in a tea spoon full per bucket". There I have to be exact. Or medication.
What to do if you need to increase the amount of greens in the diet or lose weight a little.
I'd then feed less bugs, less of those veggies with higher calories than previously at least for a while.
