I agree there is no reason to worry, yet. Of course, that doesn't mean we won't worry anyway, but there is no good reason to do so. For all you know, you have been .04 for most of these 7 years. If that is so, it took you seven long years to increase from .04 to .06. That is a minuscule change. Even if you were way lower than .04 all of these years, you are still dealing with a very slow increase. Considering your pathology, you should stop worrying about
this for a while. So do that!
