Since you already have a pretty high Na and the Cl is unknown, I would not add table salt. 50% RO looks like a really good starting point. If your mash pH is on target, your RA is right. If your yeast floccs out well, you have enough Ca. If the beer tastes snappy and bright, your SO4:Cl2 is good.

One thing you should be aware of is that unlike most of the rest of the country the water profile here in Az changes quite a bit throughout the year. These changes can be pretty drastic during the monsoon season. They also vary quite a bit within the system depending on which well/wells you're closest to. The values you have are most likely an annual average for the whole system and should be used with that in mind. FWIW I buy RO water and build it up July through September.

The values I was given were from april testing, they sent me the test results for about a years worth of tests, all fairly close, Maricopa is on its own well system, and tests each seperately, they sent me the info on the well that my street is on, they called me to get my address so I would recieve the right information. they did state that the published water info available on their website is an average of all the wells.

Yeah, the humidity goes through the roof, but it never rains anymore, maybe thats why my water numbers seemed not to vary much since last year.

I guess in time the knowledge of what does what becomes second nature, like looking at a recipe and knowing what it should taste like?
Like 944play said, you've already got a whole bunch of sodium in there. Adding 3g non-iodized salt is going to increase the sodium even more, but won't change the RA one iota.
I agree that adding NaCl will increase the chloride concentration, but so would CaCl2, without the risk of overdosing on sodium.
As for achieving a "balanced" Cl to S04 ratio, this depends on the type of beer you are brewing. A "balanced" pale ale would be described as "bitter" or "very bitter" in the EZ spreadsheet.
I'm not saying that the EZ spreadsheet is wrong, just that the definition of "balanced" depends on the type of beer that you are brewing.
