# A3 wallet age / creator age test (#708), 10 Oct
Base: mc5 band sim (/tmp/a3_t7.pkl, n=290, tp5 mean 1.03). Script z3.py. Data: dataeng3 creator_age.csv (81% coverage), walletage_first20.csv (24% coverage, n=70 only).
- Creator nonce at create: <=1 1.24 (n90), 2 1.37 (n68), 3-4 1.36 (n20), >4 0.84 (n58), no data 0.73 (n54). Halves not stable (1.41/0.47 in the 2 bucket). Serial deployers (>4 txs) mildly worse; no row = worse (confounded with coverage).
- Funder kind: internal 1.24, tx 0.97, none 0.73. Weak, no stable halves.
- First-20-signer wallet age: only 70 pools covered; fresh-wallet share <=0.1 gives 1.79 (n36), old median age 1.87 (n18), others 0.8-1.2; no consistent direction, too thin.
Verdict: no usable wallet-age/creator-age filter in the mc5 band. Creator nonce>4 skip is a possible small filter (0.84 vs 1.3) but halves noisy; park. Wallet-age needs coverage >24% of band pools (ask dataeng3 for band pools only) before retesting.
