← next-up(day@date) / next-week(day@date;weekstart) — which ‘next Friday’?
Measurement result
Current-tokenizer cost (Δ, worst tokenizer)
-2 tokens on the named current tokenizer(s) compared with standard English
Reported interval: -3.5 to -2
The result is on the helpful side of this metric's neutral point.
