I moved all my components over from the P2K frame to the P3 frame and did another round of Chung testing. I'm not surprised at the results - the frames are identical except for the seat tube and seat stay shapes.
My average of three Chung test days on the P2K was CdA=0.231. My CdA on the P3 was measured today at 0.232 in perfect, calm conditions - very clean data. At least I'm finding the method consistent; and apparently I did a good job of getting my setup the same on the P3 as on the P2K (most drag is the result of body position).
Any changes from here on out will be with body position.
