First-turn measures

All four describe RUBEL used as an opening guess. Entropy is the same idea as “avg ruled out” on a log scale: a higher number means the guess splits the possible answers into more, smaller groups.

0.0% Exact match
93.9% Avg ruled out
Higher first-turn entropy than about 80% of evaluated openers
