BMI has some great benefits, in that it’s really easy to get and you can’t mess it up. That’s why it’s a great measure for population and an amazing indicator for individuals.

BMI = Heigh / (weight * weight)

anyone who made it halfway through highschool can do this

BRI = 364.2 - (365.5(sqrt(1-(waist circumference/(pi*height)^2)))

I had to tripple check if I got the correct number of brackets, that’s how easy it is. And note that this isn’t even the useful number that’s used in the supporting paper. They validate their model by adding in other factors for waist and hip circumferences, age, height, gender, ethnicity, and body weight, to get bodyfat percentage and visceral adipose tissue.

BMI is a spherical cow in vacuum, simple, easy, and close enough in basically all cases. And when it’s off, it’s usually off in being too conservative. BRI is a great tool for healthcare profesionals, but it requires too many measurements and too much math for the average person.
