Adjustments for temperature, colour of target, variations in the users eyes and any other variation in the scope could be easily compensated for. You wouldn't need separate index marks for normal and cold temperatures.

Once you know the reading for each distance compensating for variations becomes simple and the more anal ones out there could easily work out distances to the yard.
Sounds complicated to me

It'll all hinge really on how clear the marks print out - if I have to put a mark every 1mm then it's going to be a raised mark that's 300 microns wide - that might be a bit too fine for you to be able to make out on the printed thing.
