A quick question on reading a 3-sheet 729 patch target. When I went to 
take the measurements, the on screen graphic was for a single sheet 729 
patch target which does not have the same row and column numbering 
system as the 3 individual sheets. This makes it very difficult to keep 
track of where you are if you stop or take a break. Am I missing 
something here? Thanks in advance for any help.
