I don't see how. The last line in your table of states looks wrong -- in order for your scheme to return to 0, there has to have been a transition, right? The true quadrature decoding would see that transition and go to -1. Your values will continue to be off by one compared to a quadrature decoder when going in reverse. The term hysteresis seems perfectly appropriate to me.

Do you still feel that the value should be the same going up as down for the 1x case as discussed in post 51? If so .. can you think of a counter example that illustrates your concerns with my logic? This goes for Joe too.

Yes,
of course the values should be the same for a given position, no matter which direction one gets there from. I don't know what example you want to see countered.
