I bought a set of Shimano SORA levers to be used with center-pull brakes (so, short-pull). They were $16. When I received them, I noticed that they (like the levers in grizzly59's post ^^) were adjustable for either short or long pull.

Looking at my new levers, I find that this "Rule of Thumb" is spot-on.
