In the final two of my three progressions, I did use the Pyramid, going by the Wiki book all the way.

In the process of finishing once again tonight with the entire process, I found a small indentation, a "micro-chip" perhaps in the middle of the blade after stropping on .5 micron diamond spray on wool and then leather. This "chip" was not there before. There is some pitting in the blade, just above the bevel, at just this point on the blade. This has now happened three out of four honing attempts. While this would point to a proper bevel not being established, all of the times this has happened, the "chip" has appeared only in the final stages, and I still believe it is being revealed as the final bits of metal are stropped away. The fact that the "chip" gets REVEALED late in the process and wasn't there before, and that it coincides precisely with pitting above the bevel leads me to believe it could be the steel itself. My stropping technique may not be the best but I'm not rolling the edge or slapping the blade about, and the spine is always on the stropping material.

I have routinely lapped all my stones, but will take time tomorrow to heavily lap the 4K, a single grit stone so I have plenty of room for that. Still, the "chip" I am referring to was most definitely not there after 4K viewed with a 10X loupe.
