Review decision

To resubmit, address

1. In the Core Signal, explicitly attribute the negative chronic-adaptation finding to a single 11-participant crossover RCT and avoid any framing that reads as settled consensus.
2. Clarify the role of the elbow flexor MT study (10.1519/JSC.0000000000002322) as an acute/proxy endpoint that does NOT bear on chronic hypertrophy adaptation, and remove any structural framing that places it as a co-equal anchor for the chronic-adaptation claim.
3. Note sex/participant-number gaps for the primary receipts in or near the Core Signal so the bounded nature of the evidence is visible to a reader at first read.
4. Tighten the 'Why this could matter' to a single falsifiable hypothesis (e.g., proxy MT tracks chronic hypertrophy under CWI in resistance-trained adults) rather than an open-ended list.

Major issues

• The memo explicitly acknowledges mixed chronic-adaptation evidence (one negative, one null), source-bounded heterogeneity in endpoint, and population, which are appropriate caveats, but the core signal still leans on a single negative RCT (n=11 crossover) as the headline anchor, making the central bounded claim only partially supported.
• The title frames 'Endpoint Heterogeneity' but the elbow flexor MT study (proxy endpoint) is the weakest link in the chain; this risks the appearance of a 2+2=5 angle where proxy data are being used to bear weight on chronic adaptation claims without sufficient qualification.

Minor issues

• Safety note acknowledges missing per-arm n and sex but does not state this caveat in the abstract/Core signal where the headline negative finding is asserted.
• The synthesis source (10.12775/qs.2025.47.66734) is flagged as 'mechanism' and dated 2025; consider clarifying it is a narrative review rather than a mechanism study.
• Title says 'Chronic Training Adaptation' but most evidence concerns strength/resistance training specifically; soccer findings are framed as long-term training adaptations but the source describes physical-performance recovery outcomes.

Reviewer note

Alpha memo is structurally sound for an evidence map: it names a bounded signal (chronic CWI adaptation evidence is mixed, with one negative RCT and one null trial in different populations), distinguishes acute proxy from long-term endpoints, and calls out safety/limitations. The headline claim is honest about the mixed/null pattern rather than overclaiming consensus. However, the central anchor is a single small crossover RCT (n=11), and the elbow flexor MT study is positioned in the title's 'endpoint heterogeneity' framing despite not directly testing chronic adaptation. Per acceptance anchors, the manuscript's own mixed-finding disclosure already disqualifies an elite accept; bounded edits (tightening attribution to the small RCT, clarifying the elbow flexor study as proxy-only, surfacing sex/n caveats earlier) bring it to a clean revise.
