Thanks Alex. You're very helpful.
Since it if obvious, by the number of clarifications that are necessary on this board, that Photoreading can be done wrong/incorrectly. I asked my question because of this possibility. Better to ask for clarification and seem worried than to "practice" PhotoReading for months incorrectly.
I get your point about worrying but you can't really "relax" with the possibility of doing it without any benefit.
now I can relax :0
