By that definition, it can’t be exactly 7 then either. 10^-7 is just an estimate that we’ve agreed works fine. To my knowledge we haven’t really tried to improve this accuracy either?

The exact value varies with temperature, so it's a "good enough for the typical variations in temperature experienced by most aqueous solutions" estimate.
