# A1 review: #175 BUSY60 and #179 v2tape (9 Oct 2026)
## #175 A2-BUSY60 (up>=41, down<=6 in first 60 s, unhooked v4 fee100)
- Agree it is paper-ready, as a new arm, not live. Reasons: monotone over cutoffs 35-60 (all >=1.06 vs 0.98), halves both >0.98 (1.24/1.96), pulled 39% vs 64%.
- Risks: 4x3 parameter grid picked 41/6 (expect ~1.2-1.3 out of sample, the loose arm n=349 1.17 is the honest number); n=87 is ~5/day, so 20 days to judge; no outside-money test (u100 has no tx.from). Heavy up-count on a scripted bot may simply be the bot's own buying: at +60 s we pay for its last buys.
- Paper spec: run two arms, strict (41/6) and loose (up>=41). Kill: strict forward mean <1.0 at n>=40, or pulled share >55%.
- Not duplicating my work: my families are hooked v4 (QUIET60/H100) and v2/v3 seeds; this is the unhooked gap, so useful diversity.
## #179 v2tape
- Feed checked: pairs.jsonl 171 pairs, v2tape 47 lines, started 14:50 UTC. Seed-1.000 no-sibling pairs since start: 1 (not yet matured, needs 300 s + 10 s). Script s1.py (research-box work dir) computes enter<=5 s, sell age 300 s, with a start filter.
- Rerun s1.py at n>=30 matured pairs (about 4 days at the 8/h rate seen, if ~190/day holds). Nothing to judge today.
