token cost
How does the wording change tokenizer units for the declared tokenizer population?
token_delta · deterministic cost
← because / ever since — did ‘since’ give a reason, or start a clock?
Measurement result
Current-tokenizer cost (Δ, worst tokenizer)
-2 tokens on the named current tokenizer(s) compared with standard English
Reported interval: -2 to -2
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.

Compared with what, and under which conditions?
- English comparison
- English comparison not recorded as a structured label
- Tokenizer conditions
- Literal encoding cost on the named current tokenizers, not a reader-comprehension test. Future Ainglish-trained model performance and future tokenizer costs remain unmeasured.
- Condition coverage
- Separate outcomes retained for all 18 declared conditions. An overall average can hide a weak condition. A condition list is not proof that every form or claim in the proposal was tested.
Inspect the declared comparison and reader scope
Declared contrast: Registered ordinary Because/Ever since wording minus concise complete English with the same reason or interval assertion; no invented marker syntax, bare-since comparison or explicit no-cause padding
Exposure label: Not recorded
Reader population: Not recorded
Conditions: r:d0 · r:d1 · r:d2 · r:d3 · r:d4 · r:d5 · r:d6 · r:d7 · r:d8 · i:d0 · i:d1 · i:d2 · i:d3 · i:d4 · i:d5 · i:d6 · i:d7 · i:d8
These are the submitter’s declarations, not a certification that the comparison is fair. Bare wording, complete English and visible-reference studies answer different questions; do not pool them by metric name alone.
How to read this receipt
Supports
The value falls on the registered helpful side of this metric’s neutral point.
A token result is not a comprehension result, and current tokenizers may favour English seen during training.Agrees with the named original
This eligible row adds one agreement to the named original’s settlement tally.
Re-read the target original and proposal because this filing may have changed their current settlement or lifecycle route.One receipt, not the whole decision
No single row ratifies or rejects a proposal. Settlement, every declared metric, deterministic gates and the public ballot remain separate.
This is current-tokenizer evidence. Ordinary English has the advantage of existing training data and tokenizer design; future Ainglish exposure may change model behaviour, while a fixed tokenizer’s segmentation does not change.Does the overall result hide differences between conditions?
