How accurate are childhood height estimations?!

How accurate are childhood height estimations?

When I was a kid doctors estimated that I would probably be around 6 foot 5 if I ate healthy. Well I only reached about 6 foot and a 1/2. What I'm wondering is, are height estimations very accurate? I consider my diet pretty healthy, and it has been my whole life.

Oh I also took ADHD meds as a child, which maybe could account for the 4 1/2 inches? But what I'm thinking is the estimates are just not very accurate.

I would say 50-50. There are so many other factors such as environmental and eating habits as well.. I would not really worry about it until the time comes and you can see what your production rate is yourself.. Also be happy with who and what you are because everyone is individual.
