Is there an abbreviations list I haven't found and updated?

Anyhow, from the updated list (http://www.poolforum.com/pf2/showthread.php/28985),
PF => pool factor.
A 120,000 gallon pool has a PF of 1, so adding 1 lb of CYA will add 1 ppm CYA CYA. A 12,000 gallon pool has a PF of 10, so adding 1 lb of cyanuric add will result in 10 ppm CYA
