First-turn measures

All four describe REFFO 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.

3.94 Entropy (bits)
247 Avg remaining
0.0% Exact match
89.6% Avg ruled out
Higher first-turn entropy than about 20% of evaluated openers
2.01 bits below the highest measured first-turn entropy (~5.95 bits)
