How this is counted: a meeting is one contest where both athletes were judged in the same division. Standing on the same stage in different divisions is not a meeting, because the two were never scored against each other. Debbie Muggli and Sandy Riddell meet that test 3 times. For scale, this database holds 12 recorded results for Debbie Muggli and 9 for Sandy Riddell across their full careers. Counted from the contest record as of September 21, 2026.
Debbie Muggli and Sandy Riddell at their peak
Peak window = the athlete's Olympia-title years where available, otherwise their best-placement years. Derived from recorded contest results. It is a span of years, not a rating.
Debbie Muggli reached her competitive peak from 1990 to 1991, her strongest placement years on record (50% win rate across 4 contests in the window).
Sandy Riddell reached her competitive peak from 1988 to 1989, one of her strongest stretches.
Score these two prime windows against each other on Prime vs Prime, where Olympia dominance is weighted for the size of the field each athlete beat.
Debbie Muggli and Sandy Riddell, beyond the scoreline
The part of this matchup a results table cannot hold, written by hand rather than derived from the record.
Debbie Muggli
The Ms. International, which she was runner-up at three years running, in 1992, 1993 and 1994, and third at in 1995. Her Olympia record improved alongside it: tenth in 1992, fourth in 1993, third in 1994, then sixth in 1995.
Sandy Riddell
The 1989 Olympia silver is the result. She placed fourth in 1991 and 1992 and sixth in 1993, from four appearances, and was third at the 1993 Ms. International.
Nine recorded contests and not one win, with an Olympia runner-up finish in the middle of them. That combination is rare enough to state plainly rather than smooth over.

Attribute Tug-of-War
Each bar splits a metric by each athlete's share of their combined total. A centered bar means they are level.
Not enough data to compare
Career attributes could not be calculated for one or both athletes.
Career Overlap Timeline
Each bar runs from an athlete's first recorded contest to their last, so the stretch where the two bars cross is the period both were competing. The marks on the bars are the years they met in the same division, one mark per year however many times they met in it. Careers that never cross can still be read against each other on career totals; they just cannot produce a head-to-head record.
Career timeline unavailable
We do not have enough dated contest results to draw a timeline.
Career Stats Comparison
These are career-long figures, drawn from the results we hold for each athlete rather than only the contests the two shared, which is why a pair who never met still has something to compare. Where the two differ, the row marks the stronger figure: the higher number, except on Career Start and Best Placement, where the lower one is better and takes the mark. A row the two are level on marks neither.

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.
