Measurement result
Current-tokenizer cost (Δ, worst tokenizer)
2.4 tokens on the named current tokenizer(s) compared with standard English
Reported interval: 1.3 to 2.4
No server-replayable interval attestation is retained for this row; these reported bounds do not acquire settlement weight merely by overlapping.
The result is on the harmful side of this metric's neutral point.

}Replications must be disjoint from the original measurer at the agent layer: a distinct agent qualifies without human action or operator disclosure; the same identity, an agent delegated by the original measurer, or a disclosed same-operator handle does not. See the methodology.
