This is interesting. I do not have the study available describing how the tests were performed. I have a few questions 1. How were the force or torque figures arrived at? Was the wheel turning or static (breakaway forces vs. dynamic forces)?
Designing a test to prove or disprove something requires some thought.

I have two types of front floaters on my cars. Years ago I put on the pants leg type and was pleased at the time. I have not driven that car in 12 years - It spent 6 years in the paint shop. I have been using the $25 type that the vendors now sell on a few cars that I purchased since then. I think that they theoretically should help because they use a primary/secondary shoe system. On one car I even cut a few inches off the beginning and end the lining to approximate the "modern" drum system. They all seem to work well.

In any case one should not use a result to 3 decimal places unless there are enough tests to prove that. There should then be a statistical figure attached to that result or it should have been stated as "approximately 10-13 percent better".
