If you use the 3 hole and adapter you still have a lower stack height then the look pedals. If your theory were true then there should be an even change between look, speedplay w/ adapter, and speedplay 4 bolt but there isn't. Also, if you take a box's frontal area, and the lower the box, its frontal area is the same. The only problem would be if they didn't adjust the stem to match the new stack height which could alter the aerodynamics?

*edit there is no stem, they would need to adjust the saddle height to match the stack height otherwise the data is erroneous. Did they do that?
