I have heard very vague descriptions : It's when the edge breaks down. A given natural won't do it; but a fast cutting synthetic is sure to.

The honing angle is set, the hone abrades right at the very very very edge until it turns up the tiniest bur (+1) you turn the razor and cut away the bur(-1) continuing along the stone until at the end of the stroke you have turned up the tiniest bur.

So if all was perfect like how i does it you hit the zero again and again. Over honing by going back and forth.

Which makes the point again from the HM's in my other thread. using just the right pressure. Too light and the bur might become exaggerated as the "0" edge floats up a little, honing happens behind the 0 thinning elongating the bur- very fragile construction.

Too much and you are flexing the actual factual part of the razor turning up a monster bur you can rip off.

just right and you force the bur into a tight curve that continually rezeroz itself.

This is a question. Thoughts?
