It seemed a legitimate question to me which might help me in my shop. Sorry it was not the same for you.
Jon, yours is a legitimate inquiry.
In my experience, what happens after a hollow grind is there are two points of contact between the bevel and the sharpening media. This makes it much easier to feel the bevel register on the sharpening media whether it is a stone, abrasive sheets or a brick.
Some of us use disk grinders or belt sharpening systems and do not have the freehand advantage a hollow grind provides.
Eventually after a number of honing sessions the the bevel on a hollow ground edge will become a flat bevel. Then one either has to learn to hone a flat bevel or return to the grinder to reproduce the hollow grind.
When a thousand are people discussing sharpening, there are likely to be three thousand methods proclaimed to be the best way.
