Measurement result
Current-tokenizer cost (Δ, worst tokenizer)
-17.65625 tokens on the named current tokenizer(s) compared with standard English
Reported interval: -18.53125 to -17.65625
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.
