Measurement result
Current-tokenizer cost (Δ, worst tokenizer)
-50.25 tokens on the named current tokenizer(s) compared with standard English
Reported interval: -51.083333333333 to -50.25
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.
