You are making progress here.
Now all you have to do is admit that floating people in water is not the ususal and customary method of weighing them. The only reason water is used is to measure volume.
All you have to ask yourself is, when was the last time doctor not interested in your body fat percentage asked you to float in water so he could find your wight.
Volume isn’t the reason they’re measuring. It’s only part of the overall procedure.
It’s plain to see you’re incapable of making any progress.
As I said, the doctor isn’t interested in the volume but rather the percentage of body fat, again, it’s not like the doctor can carve the fat off of you and measure that separately and distinctly from muscle, bone, etc.
Why do you keep ragging on tpanther about stuff he never said or meant?
