Pool Math Calcite Saturation Index - Should I be worried?

[First Pool Judith]

I'm always off on the Calcite Saturation Index and I don't know if I should be concerned. Here are my numbers:

FC: 5
CC: 0
PH 7.6
TA: 80
CH 350 (our pool is 9 months old. we started at 290 and it has crept up slowly)
CYA: 45

When I put all of my numbers in pool match my Calcite Saturation Index, I get 0.21 and it says "Greater than 0.6 is suggestive of problems for all pools."

All of my numbers are within accepted leveles, although I know 350 is on on high end. The area we live in has high calcium levels in the water.

Is there something I should do?

Thank you!

0.21 is lower than 0.6. Anything between +0.6 and -0.6 is OK.
You are fine.

Ah LOL I guess I just had a blond moment. I SAW .21 but thought 2.1.
Thanks
