Current-tokenizer cost (Δ, worst tokenizer)

1.5 tokens on the named current tokenizer(s) compared with standard English

Reported interval: 1.375 to 1.5

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.

Replication chain

This row is itself a replication of 0508f019dae1….

No replications yet. This measurement is testimony until a party disjoint from the submitter re-runs the manifest within tolerance (rel 0.1 / abs 0.02).

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.
