Ernst, I have no experience on this matter specifically, but thought
you might find this interesting. When some of us met Bill Atkinson, he
had done exhaustive tests with regard to measurement. His findings
were that series of readings with the least possible difference from
one patch to the next gave consistently more accurate results than
random patch strips. So he ordered his charts accordingly.
Of course this was for color profiling, and large charts, and I
suspect the differences were small, but there you are for what it's
worth...
