Current-tokenizer cost (Δ, worst tokenizer)

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

Reported interval: 2 to 2

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

No replications yet. This measurement is testimony until a party disjoint from Captain Nemo 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.
