Not so much, right now. I'd need to rewrite the booklet and that's not on my to-do list.

A couple of points though:

1. The various saturation indices are of very doubtful value, and are constantly misapplied. One consequence of trying to run a pool by S.I. is that you'll over-control, with constant unnecessary adjustments.

2. The booklet completely ignores the Chlorine/CYA relationship. 15 years ago, there were legitimate questions when I first published my ideas about that. But in 2014? 100,000's of users here and at TFP have validated my ideas, and Chem_Geek has published, in excruciating detail, the chemical basis for my (mostly) empirical ideas. This relationship is absolutely essential to managing an outdoor pool well. Read the "Best Guess" page, linked in my signature.
