The concrete detail that helps explain the median Arc settlement measurement is the scale of the measurement: the figures come from "thousands of submitBatch calls on Arc testnet," with x402 batched settlements finalizing in roughly 180 milliseconds and a measured median of 178ms . The same source provides the p95 figure of 240ms within that same reported measurement set, and attributes the sub-second behavior to Arc's BFT consensus delivering sub-second finality, meaning a Gateway-batched payment confirms in well under a quarter second and is not block-time-bound like an Ethereum L1 transaction . No concrete detail beyond these reported figures and the BFT-consensus explanation is supplied in the available passages; the abstract does not describe the measurement methodology, testnet conditions, or how the median and p95 were computed. The other source (S1) concerns Arc performance scores for green buildings and does not address settlement latency, so it provides no supporting detail for either measurement.

Sub-claim "What concrete detail in Arc Settlement Benchmarks helps expl…": 10% covered — The only gathered source (S1) is an Arc performance-scores PDF about green-building metrics (reference-set scoring for energy/water/waste), unrelated to Arc settlement benchmarks or median settlement measurements. The skipped source 'Arc Settlement Benchmarks — Measuring x402 settlement latency on Arc' is only a preview mentioning benchmark methodology and results, not the concrete detail itself, and was not read. No supplied passage provides any concrete detail explaining median Arc settlement measurements.
Sub-claim "What concrete detail in Arc Settlement Benchmarks helps expl…": 10% covered — Same as above: S1 concerns building performance scores, not settlement latency. No passage addresses p95 settlement measurements. The relevant skipped source is unread and only a title/preview, which cannot supply the concrete detail.
Both sub-claims are essentially uncovered (0.1). The directly relevant source, 'Arc Settlement Benchmarks — Measuring x402 settlement latency on Arc' (item:11203a0e-e458-421d-9722-a6a243f1f779, $0.003), is affordable within the $0.015 remaining budget and is the most likely to contain the concrete methodology detail explaining median and p95 settlement measurements. Recommend buying it first. Other candidates (e.g., 'Web Payments Review — How long do x402 payments take to finalize?', $0.002) are lower priority and only general overviews; buy only if the primary source proves insufficient.

Final coverage assessment — The question asks what concrete detail in Arc Settlement Benchmarks explains the median and p95 Arc settlement measurements. The only relevant source is S2, which reports the measurements (median 178ms, p95 240ms) and attributes them to x402 batched settlements on Arc testnet, with Arc's BFT consensus delivering sub-second finality. However, the source is an abstract and does not provide the concrete methodological detail (e.g., how the measurements were collected, what submitBatch calls are, sample composition, or measurement procedure) that would explain the median and p95 figures. S1 is about Arc performance scores for green buildings and is unrelated. Thus both sub-claims have only a partial answer: the measurements and their stated cause are given, but the concrete explanatory detail is missing. The assessment does not establish a complete supported answer for every requested part.
