I'm asking about rate of change, not absolute numbers so the assumption
of not changing the surface area and hull form is valid. It's an element
of calculus if you have studied mathematics. To give a realistic
example, change the hull from smooth to one of those lapstrake types.
Leave out drag and reread the first three words of the title: "Rule of
Thumb".

Rule of Thumb does not normally call for a knowledge of calculus...
