Man, are you a vampire? Do you not cast a reflection?
Why are you so dismissive to the idea that the way you LOOK is what really matters? Besides that then the only way to go is to get the accurate weekly bodyfat assesments.
But on the other thread you never said you didn't like the idea of looking in the mirror. You know? So if you tell people that you don't want to take their advice that will help to narrow down your options. Otherwise we'll just think you didn't hear what we said. I'm just saying this to help you get your answers.
If you must be that precise then bf measurements are the only real way to do it. The scale is bound to show little fluctuations and of course you could be gaining muscle weight. The problem is people have a lot of trouble with calipers.
