Jandy SWCG's "optimal" water conditions: why raise CYA?

[BigTallGuy]

NOW raise it up to where it SHOULD be (around 80 ppm), drop you TA to 70 if it is higher than that, and start saving money on acid and maintenance and stop being a big tall dumb guy and become a big tall smart guy!

I ordered my Taylor K2006 test kit via Ben's link and I am waiting for it to arrive so I can do proper testing. You may remember that I had an extremely bad experience with CYA a few years ago and I would like to know who sets the 80 PPM standard for SWCG Pools, and why.

My SWCG owner's manual says 50 PPM of CYA, and I believe I read one of ChemGeek's post that says the higher above 50 you get the CYA, the more it actually counter acts with chlorine. In addition, I still need to run my filter at least 4 hours a day for a good turn over.

SO HERE IS MY QUESTION TO ANY AND ALL POOL OWNERS WITH A SWCG THAT KEEP THEIR CYA AT 80 PPM AND THEIR CHLORINE AT 4.0 OR HIGHER, DO YOU EXPERIENCE OR GET COMPLAINTS ABOUT BURNING EYES? BE HONEST, BECAUSE THAT WAS MY EXPERIENCE.
