I think in the hypogonadism (i.e. not steroid) world, you're supposed to be within the range. Is there damage from being 60% over the top? I don't know.
I know that if you get used to that and then have to live with T of 700 (out of 800) then you won't feel too good in comparison. I think most docs would reduce your dosage, so this has to be a real concern.
Also, your E is high as you pointed out. Remember that E is made out of T. My guess would be if you had T of 800 (still top of range), that the E would drop down within range by itself.
