Is there chart or formula that shows relationship between CYA and %FC loss per day ?

[steviek]

I'm looking for a chart that would show the CYA vs %FC loss per day, given say water at 85 degrees, and in Texas with full sun on pool.

The reason I'm asking is I want to confirm my CYA testing is ballpark and I'm getting the expected loss.

I don't know if this is exactly what you are looking for? Pool Water Chemistry
