Like cooking food, following a recipe strictly is a very good idea at first. But, with experience, tweaking, tasting and fiddling around seems inevitable. Just from years of experience with developing and printing, I can do many things intuitively now that would have been risky or disastrous early on. Still, I always keep notes on a legal pad. Toning, however, is always done by eye. Haven't figured out yet how to be empirical about it since there are so many variables, and so many nuances that depend on the image.
Provides just the right amount of variation that allows you to judge quality!

Now if I go in again, I'm going to have to find another way to get it the way I like, they are going to have to fiddle with the "recipe" to suit my taste.
I was wishing for something like a 21-step Stouffer scale for coffee because there just isn't any measure I know. Do you check for baume? Do you check viscosity? Color?
To be truly scientific, you need to take the next step.
Based on your experience, develop a hypothesis about why or how something is or will happen, and then figure out a way to test it.
So as an example only, you might do something like refine a process at a particular temperature, then develop a hypothesis about what the effect of a change in temperature might do, and then test it.
