It needs to know the user's height in order to calculate BMI. And to avoid entering it everytime, the user steps on the scale first to tell the scale what the user's weight is. The weight serves as a "user ID" of sorts. This makes it possible for everyone in the family to use the device without having to change the user setting. Dad is "180;" Mom is "140;" the teenage daughter is "110" for example.
But when it gets "190," it can't find a user height. In this case it doesn't calcuate BMI and defaults to showing just the weight.
Waist = 43.75"
Height = 5' 7"
