> Does the Spyder read single patches or rows? 

The PFP 2 that I use reads individual patches.  I think it's the best 
way to go for reading 21-step test files, which is what I do.  I do 
not read large targets with it.  I don't think it's necessary, and a 
strip reader is what I'd want for that process.

Based on some comparisons I've seen in the past, careful manual 
reading is slightly more accurate than strip reading.

With my 21-step test file,

I don't have significant errors. (I have put a white dot on the PFP 
reader to help alignment.)
 
It takes one minute to read 21 steps, and that is all I find is 
needed.
