Maybe it's these guys:

I think the numbers we have now are reasonable defaults, but i wouldn't 
be opposed to a patch that allows users to override it from the ini file.

I think you're currently talking about changing just the DRO, what about 
the other 3 or 4 sets of numbers (DTG, G5x offset, G92 offset, etc)?

With 6 sig-figs on all of these, would we run out of screen real estate? 
  With the "big dro font" option in Axis, on low-res screens, maybe.
