mean-outcome / likeliest-outcome — an expected result need not be a possible result
Not yet counting in evidence decisions. This row remains available for assessment, but does not currently carry a counting evidence result.

How does the wording change tokenizer units for the declared tokenizer population? - Reported result
- -0.625 tokens per declared item
Reported interval: -1.875 to -0.625.Fewer tokens on the named current tokenizers; this is the encoded-length difference, not the proposal decision.
- English comparison
- English comparison not recorded as a structured label
Declared by the submitter; not a certification of equivalent information.
- Tokenizer conditions
- Literal encoding cost on the named current tokenizers; not comprehension.
- Named instruments

- Conditions covered
- No condition-by-condition settlement contract recorded
An overall average can hide a weak condition. A condition list is not proof that every form or claim in the proposal was tested.
- Settlement role
- Awaiting independent settlement
An original reports one result. It does not confirm itself.
- Is this result within the cost allowance?
- This headline is within the allowance.
The reported difference is -0.625 tokens; the current declaration allows at most 6 tokens.
This compares Ainglish minus English with the current declaration, which may differ from the declaration when the result was filed. It checks the headline only: inspect any required per-form and per-tokenizer results too.
- Has the original estimate been independently reproduced?
- Awaiting independent settlement.
An original reports one result. It does not confirm itself.
Reproduction asks whether fresh-input findings agree under the settlement rule. It does not ask whether either value satisfies the cost allowance.
Being within the cost allowance is not a completed prerequisite. Reproducing an original estimate is a separate check, not proof that the allowance is met. Current evidence status, settlement and every declared result still determine readiness.
How can one check pass while the other does not?
For example, an allowance of at most +3 tokens and an original estimate of +3 ask different questions. A replication of −0.5 is within that allowance but may disagree with the original. A replication of +3.25 may reproduce +3 within the settlement tolerance while exceeding the allowance.
These are illustrative numbers, not a new settlement rule. A cost saving is not a comprehension result, and a reproduced premium does not by itself mean a proposal should be adopted or rejected.
Inspect actual inputs and recorded answers
The comparison label is the submitter’s declaration, not a semantic certification. Check that both versions preserve the information needed to answer the same question.
Numbers count only readable inputs attached to this receipt. They are not the experiment’s declared sample size or the number of reader calls.
Showing 1–6 of 8 readable, inline study items, in stored order—not a selection of successes. 0 control items are kept separate.
Each result has its own input pages. Positions across the two studies do not imply matched cases.
Input 1
- English input
- machine-v1 models one output count: P(0)=9/10 and P(10)=1/10. Under machine-v1, the probability-weighted mean is 1.
- Ainglish input
- machine-v1 models one output count: P(0)=9/10 and P(10)=1/10. 1 is mean-outcome(machine-v1).
Input 2
- English input
- machine-v1 models one output count: P(0)=9/10 and P(10)=1/10. Under machine-v1, 0 has the highest outcome probability, ties allowed.
- Ainglish input
- machine-v1 models one output count: P(0)=9/10 and P(10)=1/10. 0 is likeliest-outcome(machine-v1).
Input 3
- English input
- plurality-v1: P(0)=2/5, P(1)=7/20, P(2)=1/4. Under plurality-v1, 0 has the highest outcome probability, ties allowed, although P(nonzero)=3/5.
- Ainglish input
- plurality-v1: P(0)=2/5, P(1)=7/20, P(2)=1/4. 0 is likeliest-outcome(plurality-v1), although P(nonzero)=3/5.
Input 4
- English input
- two-point-v1: P(0)=1/2, P(10)=1/2. Under two-point-v1, the probability-weighted mean is 5.
- Ainglish input
- two-point-v1: P(0)=1/2, P(10)=1/2. 5 is mean-outcome(two-point-v1).
Input 5
- English input
- two-point-v1: P(0)=1/2, P(10)=1/2. Both 0 and 10 have the highest outcome probability; neither is a unique mode.
- Ainglish input
- two-point-v1: P(0)=1/2, P(10)=1/2. Both 0 and 10 are likeliest-outcome(two-point-v1); neither is a unique mode.
Input 6
- English input
- distribution-A: P(5)=3/10, P(15)=7/10. Under distribution-A, the probability-weighted mean is 12.
- Ainglish input
- distribution-A: P(5)=3/10, P(15)=7/10. 12 is mean-outcome(distribution-A).

These are the study author’s declarations. A finding applies to this tested scope; this summary does not establish that another study is comparable.
Absolute arm results, reader-specific results and condition results below are retained values, not a newly pooled analysis. Accuracy arms use fractions from 0 to 1; their difference uses percentage points.
