I have to agree with this sentiment.

Considering the lengths gone to just to get accurate measurements here for these calculations, and the disagreement about what those calculations should be I'm getting the sense that this is not something Joe, Tim, Josh, or even Maestro Levi figures out before they start grinding away on a piece of soft steel. I for sure doubt that even Mike Blue could be knowledgeable enough to reach the fractional tolerances required by these calculations when predicting the size changes through the tempering process.

So in other words, the Spine angle predicting the honing angle is less a deliberate and accurate attempt to get the perfect edge and more a happy accident we take advantage of when trying for the finest edge possible, and sometimes we are willing to compromise the very finest of edges to preserve beauty or ease our task.
