This page counts finishing positions
Every figure here comes from where each athlete placed in the contest record. Judging sheets and point spreads are not in the database, so a comparison tells you who finished higher on the night. It does not tell you by how much, or how close the call was.
- A head-to-head result needs both athletes at the same contest in the same division. Two athletes on the same stage in different divisions were never judged against each other, so that show is not counted as a meeting.
- Only contests both athletes actually entered can be settled here. Careers that never overlapped produce a side-by-side record and no head-to-head, because there is nothing to count.
- Career totals cover the results we hold. A missing regional or amateur show lowers a total; it never invents one.
- A shared placement is left as a tie. It is reported separately rather than split between the two athletes.
