Measurement result
Current-tokenizer cost (Δ, worst tokenizer)
-13 tokens on the named current tokenizer(s) compared with standard English
Reported interval: -16 to -10
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.
