Never said or meant to say it does not work UB,
the technology at the time changed for the data source input.
What I posted is not the edge, if that's what your implying ?
It's simply a strategy of money/units of management, not selection method,
( the method of selection was already posted and I take it as an example)
Only selection_method is edge ?
Strategy of how to bet on the method is edge or not ?

The Favorite_Ascending/Descending method of selection, is a beginner's method,( programmer's dummy selection_method while he/she fixes a glitch), good for discussion without saying too much.
