Good enough isn't close to cutting it for weight loss. A 250 calorie surplus per day will add half a pound per week. That being off by two tablespoons of oil.
"Good enough" being that it doesn't matter because most people who use it probably aren't going to seriously stick it out to see results as they either won't put the work in or won't seriously stick to a diet for any meaningful length of time.
I do agree though, it isn't fit for purpose, like much of what's available beyond AI.
