The `DataMappingMode.OpenInterestAnnual` summary said the contract maps when a back month has a higher volume. The map-file generator compares open interest for both open-interest modes; they differ only in which back months they consider. The wrong word came from #6436, which fixed it on `OpenInterest` and copied the old sentence into the new member.
The docs page renders these summaries verbatim, so users read the wrong rule there. Also fixes "that" → "than" on both summaries.
