Also the suggested profiles in the OP are probably quite conservative as far as mineral content goes, I have been gradually increasing the amount of chloride especially in my brews and really liking the results.Yup - hence my comment about using their profiles with caution
Ah, ok, that's interesting to note - thanks for the tipAlso the suggested profiles in the OP are probably quite conservative as far as mineral content goes, I have been gradually increasing the amount of chloride especially in my brews and really liking the results.
Not crazy at all, my last milk stout had 250ppm chloride and it certainly doesn't taste minerally. In fairness the sulphate was relatively low at 60ppm, but still Bru'n Water suggests 10-100ppm as the ideal chloride range.But playing around in BF it looks like if I add 2-3g CaCl it'll push the Cl content up towards 150ppm which doesn't sound too crazy, and a SO4:Cl ratio of 0.4 or even 0.3 (and Ca is still below 200ppm).

Thank you and no I didn't as I am not aware of these reports.It is there

Thanks for clarifying, much appreciatedThe purpose of the alkalinity value is to try to hit the correct pH, that's all. So if you're using software of some kind then simply adjust the alkalinity until the pH is where you want it. The fact that you got a predicted 5.15 pH demonstrates the fact that these alkalinity values are very general estimates, and the actual pH will depend greatly on the specific grain bill used. For example if there's a lot of dark crystal malts this will push the pH down and so will require a higher alkalinity.
So to answer your question, you should prioritise pH over alkalinity, however for those who don't use predicting software then targeting alkalinity will usually get you in the right range.
