It's not there yet.
I removed most of the aspen from under the hides so now there's two layers of newspaper and just enough aspen to cover it.
93 degrees on the glass - 78 degrees on top of the aspen in the hide.
The only other option is to remove one layer of newspaper. I doubt this will raise the temp 12 degrees so I may just have to raise the temp over the recommended 95 degrees.
