First-turn measures

All four describe LUPIN 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.

4.59 Entropy (bits)
210 Avg remaining
0.0% Exact match
91.2% Avg ruled out
Higher first-turn entropy than about 57% of evaluated openers
1.36 bits below the highest measured first-turn entropy (~5.95 bits)
