i dont know for sure, but if the scale on the dial continues on in the same manner I'm guessing about 95 or so....hot. yearning for some tropical weather?
 
I have the common 5 degrees or so off problem. I had to adjust it somewhere between 65 and 70 on the dial to get 72 in my house. I noticed the scaling they printed on the t-stat does not look linear. I measured the sweep of the knob and came up with a 300 degree angle. If the scaling is 58-90 then my current knob position looks to be about right for 72 degrees(43.7% of scale). My next idea is to make up a new scale out of paper and see if my guess is right.

Also, the hole behind the t-stat is sealed no drafts. It is mounted right next to my other t-stat. See pic..

 
yeah, i usually just advise loosening the set screw on the knob and affix the knob at a more appropriate position.....they always seem a few degrees off, at least its consistent.
