First-turn measures

All four describe OZONE 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.

3.81 Entropy (bits)
287 Avg remaining
0.04% Exact match
87.9% Avg ruled out
Higher first-turn entropy than about 15% of evaluated openers
2.13 bits below the highest measured first-turn entropy (~5.95 bits)
