I had seen this mentioned before, probably by you (elsewhere), and didn't get the point at that time. The eliminations are more important.
It is a sort of caveat emptor, where if you take the "easy way" (set instead of eliminate) you may lengthen your solving path.
Interesting, I am siding with ronk on this one!  |
