This is what I do too, and it does make a lot of sense, especially if you have bikes with somewhat different crank lengths, pedal thickness, saddles, and/or with different saddle setbacks.
It is at least a good way to check a potential bike purchase or do an initial set up on a new build. But then you have to fine tune by riding it.
