There are basically only four variables. Cutting one pass with full power leaves only 2 variables with each species of wood, no matter what the job it is what cutting speed is best for that species of wood that is the main concern, so a set of tests per species kept as a reference can be used for any job and suggest alternatives as well,
I use this design as it uses the least amount of wood but it can be more obscure to figure out, larger test systems are more “in your face” but also use more wood. You can pick the style you are comfortable with and as you use more types of wood build a larger reference set and eventually barely need to refer to it.
