I don't mean to knitpick, but since the topic is accuracy, it seemed relevant. Your numbers don't jive with mine (so to double check, I did online searches of several sites).
I'm wondering if you're using a resource that isn't taking the fiber calories into account (but that wouldn't really explain it, either, because I couldn't find a single source that listed 1 cup of cooked kale as having 80 calories).
According to what I've found, 1 cup (88g) of raw broccoli containes about 30 calories and 1 cup (also 88g) of raw brussels sprouts have 38. That's not a huge difference.
After cooking, brussels sprouts cook down more than broccoli, but not drastically unless you're frying them or roasting them for a prolonged period of time.
That's why I generally measure my veggies raw, even if I'm going to cook them, because "shrinkage" can be so variable.
I checked several calorie counting sites, and they all l listed kale as boiled Kale as having 36 calories or less per cup, and the 36 calories was counting the calories in the fiber. When the fiber calories were subtracted, the calorie count was actually only 16 calories per cup (you can subtract the calories coming from the fiber, because fiber is a carbohydrate that humans cannot digest).
The calories don't count because humans can't break down fiber (cellulose) and it leaves the body entirely intact and unburned.
What that means is that high-fiber plant foods have more useable calories to a horse or cow (because they have gut bacteria that can break down cellulose) than for a human being. We would starve to death if we were to try to eat hay, because virtually all of the carbohydrates are cellulose. We can't get at those calories, but cows and other animals can (and just trivia - only termites are able to digest fiber without the help of probiotics. Mammals that can digest fiber are not born with the ability, it get's passed along to them from their parents (in a kind of gross way, that I won't mention but you can look up).
Since calorie counting resources are aimed at humans, I think it's quite strange that they all don't subtract the fiber calories, but some do and some do not (and almost none tell you whether they have or haven't subtracted those calories - you can only tell by checking the math.
Because humans can't digest fiber, the FDA allows food manufacturers to subtract fiber calories, but does not require them to.
It seems to me that they all should be required to subtract those calories, because it creates a misleading impression that high-fiber foods are higher in calorie than they are in actuality.
