I've been operating on the info I found online about my local water, but I haven't obtained my own report so if it's changing I don't know about it. It's so soft that I haven't worried about it too much:
Total Alkalinity CaCO3 42
Based on my last round of research, I'm aiming for an SO4 concentration of 300ppm or just below, and a Cl/SO4 ratio of .12-.13. This is for an IPA.

I'll assume you meant to say "isn't relevant." But that's where I'm curious about what people "mean" when they say that a certain concentration of [some brewing salt] will produce [some affect on flavor] - does this mean a concentration in the mash? In the boil? In the final product?
I understand that matching a water profile from historical data or geographic region comes down to matching the original water, but that's not what I'm asking. I don't care about the water in Dublin or Denver, I want to build water that will give me a good product for my system. Even saying my water is the same as all the great Bend breweries isn't really true, because they all build their own water in-house anyway.
But I mainly just want to know what the convention is so I know how to read it when somebody says "shoot for X ppm of sulfate" - in the mash, kettle, or what? I've heard of people adding salts to their strike water, then leaving some behind. I've heard of people adding them to the mash tun. I've heard of people adding salts directly to the kettle. All of these will result in something different, right? If I calculate 300ppm of SO4 in the kettle and it was meant to be in the strike water, I could be much higher than I want to be. I realize there's a lot of personal taste involved in this, but I like to get it right early on instead of going back to the drawing board too many times.
I have seen the Bru'n sheet but every time I look at it I just go back to the EZ sheet because it's . . . easier.
I'll keep trying both of them to see which suits me best.
Thanks for the replies!
