Quite correct Neil. Lou has no clue about SPF, other than what the letters stand for. He doesn't know how it works, doesn't understand that EVERY poolplayer on Earth does some sort of SPF process (some are much more accurate than others)...and most certainly doesn't realize that he does it himself. I offered to bet him serious money that I could prove it, but so far he has declined. I suspect things will remain that way. That's how it is with closed-minded individuals. You don't know what you don't know! :thumbup:

Lou, and I mean no disrespect by this, but you are only showcasing the fact that you really have no idea what instructors really teach or why they teach what they do.
