I agree with that statement, David. On my second target I decided to 
try using ruler to guide the Spectro. It seems that the ruler, while 
certainly helping to keep the Spectro along the row, was actually 
slowing the process down (at least in this simplest -just the ruler- 
implementation). Time spent aligning the ruler along each row 
(certain distance from the edge) plus the effort to keep the ruler 
in place while reading the row plus you still need to make sure that 
the Spectro is correctly over each tile... In the middle of the 
target I turned back to the 'unruled' approach. It was faster and 
required less effort (especially since margins on the page were 
minimized which made patches bigger).
Maybe if one would implement the ruler with some sort of frame with 
guides and paper holder...
