I googled to see what I'd find. Found claimed increases of 10%, 20%, and one as high as 10x (think someone meant that x to be a % sign!?). I'm more of a recreational rider, and use mtb platform pedals, but I did buy and try some clipless pedals. I could tell my efficiency was increased, but didn't like that I couldn't move my foot around to a different position on the pedal, so went back to my platforms. Not a big deal for my type of riding, and what little of it I get to do.

Once into the toe clip, you pushed down to engage the pedal and pulled the leather strap tight. I had wooden sole racing shoes for stiffness and cleats which were state of the art at that time. Once you locked into these, you could not get out without reaching down and they were not comfortable.

In Andy Pruitt's book he recommends the clipless for more power output, but he didn't give any figures. I feel they helped me, but others say they don't.
"...This placement works best for men's size 9 feet (European
sizes 41-42). Riders with longer feet will need more stability
and should move the cleats further back on the shoe to put
more of the foot in front of the pedal axle. In contrast, riders
with shorter feet..." You get the rest.

I'm curious lpress, did you weigh the pedals and shoes?? Were the shoes
about as stiff as one another?? I don't wish to seem to be taking pot-shots
at you because you actually tried empirical analysis while I just sat at my PC.
There have been studies of how to pedal better but clipless is just a given.
That is true even with instrumented pedals. You might find High-Tech Cycling
by Ed Burke interesting. It was published in '96 and I found it remaindered.

Part of the appeal of the Internet is that non-experts can make valuable contributions. Discussing my amateur experiment with clipless pedals has been fun and illuminating -- if each of us did one such experiment, we would learn a lot!
