Just had a quick question about your measurement technique...

When you are measuring the samples 3 times, are you reading the 
patches dark to light (or light to dark)in a complete pass, and then 
making 2 more passes, or are you measuring each patch 3 times and 
then moving to the next patch? Owning an old DTP22, the accuracy 
seems to be higher if you measure the entire strip, and then start 
over. Something about multiple readings of the same patch seems to 
make it less accurate. Why? I have no idea, my i1 does the same thing.
