Me too, I'm usually in the 75-78 range.
Johnny, the focus is so critical that there is even play within each number. Set it to whatever focus number you think is closest and then play with it back and forth while keeping it at that number. You should see a difference. If it gave a readout of 11.8 or whatever, then that might work but whole numbers are just too coarse to judge by.

In my opinion this is one of the most important parts in making an image sharp with an adapter.
