I hope Stuart continues with SB, as pointed out, the criticisms are not of him. I don't think there is any "holier than thou" either. Experienced instructors just pointing out facts. We all know that some like Stuart (and myself) could do 4 dives wet in that temp. water quite easily, especially if the weather is warm enough for the SIs. But the standard is there. Many people would find this cold. There is the possibility of hypothermia, or at least poor judgement due to contending with cold. So the standard exists to protect all. Much like a lot of the laws we have today--how many times does one think "Geez, what a stupid law we just don't need"? Then there is the self regulation we have which so far keeps the govt. out of scuba.
Personally, I would find doing all 4 checkout dives in one day to be an awful lot mentally. I don't know if it's the same shop that I googled, but there is one in that area that does all the classwork (ASSUME e learning) and pool dives in ONE DAY. As I've often posted, I'm glad I didn't take the weekend OW course with TWO pool days. How much can you cram into your head at once?
As far as "conditions" and "fudging"-- You have to find a way to keep it within standards. I know of a LDS in Miss. that does their OW checkout dives on the FL panhandle. They scout out motels over there and set it up for the students. It's a 3 hour drive, so the motel night makes it easy to do in 2 days.
