I need your experience regarding creating Device Link Profile ( CPS

Does it make sense to select an output layout with a big number of patches ?
I'm talking about "Optimize a Device Link" (Iterative match to a standard) Option.
I don't see real big improvement measuring 234, 928 or 1485 patches.
I create profiles on Laser printers that are stable and accurate but...

So any comments will help me .
Thanks in advance
