High calcium hardness-should I be concerned?

I usually test CL and pH daily and everything else one a month. Today's numbers:

FC: 5.5
PH: 7.5
TA: 40
CH: 590
CYA: 50

I will bring up both the TA and CYA according to Pool Math. My CH is consistently high though every time I test it even when all my other numbers are good. It has dropped from a high of 640 in March to what it is now. Here in Central Florida we are in our rainy season and I have had to drain off several inches about 2 weeks ago.

Is there any damage that could be done with a higher than recommended calcium hardness level?

Use a 10 ml sample for the CH test. 10 drops of R-0010, 3 of R-0011, then multiply R-0012 by 25. When you get to those kinds of numbers, whether you get 575 or 600 instead of 590 doesn't make a lot of difference but it does save a lot of drops. If the color is too faint, use more R-0011

Good to know! I hate using that much reagent.

You mean multiple by 25ppm/drop, right?
