You're missing the point. Do you really think you're turning us on to something new here? Of course you tune the ratio with your pinion and spur but unless you know the final ratio you hope to achieve you're not doing much good. Why are you fighting this fact?
The chart can show you what your ratio will be with certain spur/pinion combos. You don't need a calculator. For example, some motors need to be run at certain final ratios for optimum performance... unless you know how to get this you'll be either under geared or fry the motor.
