# why ranked

Overall: #25 — score 28.7 ● medium — one signal missing, weights renormalized

signalweightinput (0–100)
aa_intelligence 0.50 23.8
arena_elo 0.30
bench_composite 0.20 41.1

missing signals are dropped and the remaining weights renormalized — never imputed.

Coding: #9 — score 22.5 ● high — all signals present
