You mean that the effect of lactic acid is 2x its expected effect? Adding 1ml of lactic in the spreadsheet seems to change the predicted mash pH by -0.075. Does this mean that the rule of thumb of -0.1 is an overestimate?
The spreadsheet is great! Thanks for putting the work into it!
I'm guessing that this request has been made before, but a phosphoric acid addition calculator would be great.
