Mike: Thought about your ? a little more. Seems to me that you've proven all is OK because you over exposed by 1/3 stop and placed the PSP to the left by 1/3 stop. I see no need to retest at 2.67.
Your test set-up/results are very interesting because meters are good to a 1/3 stop and one can get the same EV reading over a range (small ?)of enlarger heights. I'd like to hear more about your test set-up-ie time of exposure,lens, etc. Thanks
