Yes, that takes out all the variables one encounters with trying to measure: type of saddle, saddle offset, saddle tilt, type of shoe, type of pedal, length of crank . . .there are probably others.
When we pedal, we measure with out legs every stroke. A little bit off adds up after 20,000 pedal strokes. Always seemed to me therefore that we should measure with our legs when setting up a saddle. I do use numbers when transferring from one bike to another after the first one's set up, as long as saddle and tilt are the same.
