First-turn measures

All four describe RADIX 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.

4.32 Entropy (bits)
204 Avg remaining
0.0% Exact match
91.4% Avg ruled out
Higher first-turn entropy than about 40% of evaluated openers
1.63 bits below the highest measured first-turn entropy (~5.95 bits)
