I go by the 'flies off the piece' method. It's my impression that the business end has to be in continuous contact with the edge before it will do that. Trying to evaluate when the wiggler stops wobbling depends on how good your eyesight is, what you use to inspect the end while it's spinning, etc. So there could be some variability there. The "preferred" approach also depends on what your requirements are!
When I use the pointed-end attachment to find the center of a pop mark, I use a machinist's magnifier to check for wobble. It can still have some wobble going on, even when you can't see it with the naked eye. These days I'd rather use the edges of the workpiece as datum coords and drive the table to where it's needed using DROs. You can't always do that so you have to use what's best suited for the task at hand. As always.
I also have an electronic edge finder & the maker says NOT to spin it while finding an edge.
I have wondered if the presence of lubricants alters how well a wiggler works. Any comments there?
