All BMI Charts are not the same

I've been playing with my GOLAS and I have found that ALL BMI CHARTS are not the same. Here is a chart from obesityhelp and weight tracker. BUT the chart from Dr.Hadley's site is different. SOOOOOO My "NORMAL - IDEAL" could be anywhere from 87-122 lb. WHAT A BIG RANGE!!!! Weight Tracker BMI Between 18.5 and 24.9 Normal 87 119 Between 25 and 29.9 Overweight 120 143 Between 30 and 34.9 Obese 144 167 Between 35 and 39.9 Severely Obese 168 190 Between 40 and 49.9 Morbidly Obese 218 45.6 Dr.Hadley BMI 16 - 20 Thin 100 21 - 25 IDEAL 101 122 26 - 30 Moderately Overweight 123 144 31 - 35 Overweight 145 168 36 - 39 Very Obese 169 190 OVER 40 Morbidly Obese 218 45.6 Just wanted to share with you all.
