Wayne, Cost wasn't my concern. I was really just wondering about the basis for the tabel and whether it might lead to unecessary overchlorination of some pools.

For acedemic purposes, It may be interesting to find out (I'm not volunteering), but if you get that close to the edge you would probably find it is too varied to have any public value.

It would be interesting to collect and analyze some empirical data (e.g. daily chlorine level and CYA, hours of direct sunlight per day, bather loads, microbe counts, algae outbreaks, etc.) from a large number of residential pools and try to find the correlations. It's way over my head from the technical, monetary, and time standpoints. I guess that's why Ben came up with the table.

Please don't get me wrong. I think the Best Guess Table is great and I'm confident that the worst it might do is cause some people to overchlorinate their pools somewhat and probably not harmfully. I don't worry very much (really, at all) about the overchlorination issue in my pool, but it's obvious from reading some of the posts on this forum and others that there are plenty of people who worry about it a great deal. If there's a safety factor built into the table maybe people could be more confident in playing around with the levels a little more without too much risk of infections and algae infestations. On the flip side of that, the shock levels in the Table don't seem to have much wiggle room; people who fail to reach those levels, even by a little, often seem to have trouble clearing algae.
