I saw a "Free Swimming Pool Test Kit" on fatwallet (my other favorite site) and had to check it out.
I am not sure what agenda healthypools.org has, but apparently the only two parameters necessary for a healthy pool are pH between 7.2 and 7.8 and FC between 1 and 3. No mention of CYA or anything else. FC of 5 is indicated as "unacceptable" and "unhealthy". Nothing like educating the public.
