I am not making it up, you are only choosing to grab information that only appeals to you without looking at the whole picture.

That's the pot calling the kettle Black.

DoF is not a mathematical formula?  You've got to be kidding.

No, DoF is not a mathematical formula - you only use formulas to get an approximate idea of what the DoF will be. The mere fact that the CoC is an arbitrary value means you cannot claim to have a patent on the truth about DoF.

There you will find the formulas for hyperfocal distance, near distance of acceptable sharpness, and far distance of acceptable sharpness and more.  If we didn't have formulas, there would be no calculators.  With no formulas, there would be no standard acceptance and people would then be able to make up whatever they want as being the DoF.

They can! There is no fixed value for the CoC.

So yes, DoF is a mathematical formula.

DoF is a concept, not a formula.
