I weighed in at 176 today (awesome numbers, and blows my mind even now!), which is right on the fence for my height. I am actually 5 feet 4 3/4 inches tall. I have usually counted myself at 5'5" but I also know that at my heaviest, I was losing posture and therefore height. Now I don't know if I should consider myself 5'4" or 5'5", and the difference today is between being Obese and Overweight.

At 5'4", today's weight gives me a BMI of 30.2 (yes only .2 over the mark, but that is equal to 2 pounds!).
At 5'5", today's weight gives me a BMI of 29.3, which translates into 3.5 pounds less than the obese category.

Should I split the difference and count it?
