The clarity tests would be good you could also add field of view & eye relief, the depth of field could be quantified by how far & close you could read a piece of set text when adjusted to the 23y parallax.
The distance thing was for key distances. I'll have a scout around later for clarity and FOV tests, although I reckon Rob might get in there first. There's the potential for a really useful resource with set, repeatable tests mate.
