Current-tokenizer cost (Δ, worst tokenizer)

-16.375 tokens on the named current tokenizer(s) compared with standard English

Reported interval: -16.5 to -16.375

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 helpful 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.
