| Value kind | observed — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range. |
|---|---|
| Scope | The endpoints are rounded MFU percentages, so a throughput ratio computed from them (54/34) is approximate; quote the gain only from the source's unrounded figures. |
