The 20 Most Pristine Quads of All Time in Womens Figure Skating

Описание: This is a data-driven ranking of the most pristine quads in the history of womens figure skating. Since this is an all-time ranking, current as of the end of the 22/23 season, it will inevitably change based on future results. As such, the plan is to release updates to this video every few seasons.

Whereas most of the videos on this channel are focused on determining the “best” jumps or jumpers, the focus here is on determining the “most pristine” jumps. Why is this and what’s the difference?

Ranking the best quads would necessitate using a methodology similar to the one used for our “top quad jumpers” videos, which factors in not only jump quality, but also jump difficulty. While this approach is perfectly sensible, the result here would be a somewhat repetitive video packed almost entirely with 4Lzs and 4Fs. As such, it was decided it would be more interesting to momentarily ignore difficulty, and instead focus on the most flawlessly executed quads, regardless of quad type and difficulty.

With this in mind, the basis for this ranking is PoM (“Percentage of Max”), a metric calculated by dividing the number of points a skater received for a jump by the maximum number of points they could have received, taking into account the scale of values that was in effect at the time of the jump.

One advantage of PoM is that it factors in not only GOE, but also the base value impact of any calls that a jump received. PoM also makes it easier to compare jumps across different seasons and scale of values.

Some further explanation of PoM...

• To use a 4F to illustrate, the maximum score at present for a 4F, ignoring bonuses, is 11.00. So, as a hypothetical example, a 4F right now with a score of 9.00 would have a PoM of 9.00 / 11.00 = 81.8%.

• When calculating PoM for a quad jumped as part of a combination or sequence, the base value impact of the non-quad part of the jump pass is excluded from both the numerator and denominator. (It wouldn’t be excluded if you were calculating PoM for the entire jump pass, however.) For example, for a 4Lz+2T, the 1.30 point impact of the 2T would be excluded. Also, it is a rare occurrence, but if a jump pass’s GOE was based on the non-quad part of the jump pass, it would be recalculated to be based on the quad.

• Second-half bonuses are factored into the calculation of PoM. However, other bonuses, such as those sometimes seen in certain novice and domestic competitions, are generally excluded. Jump sequence adjustments, which were relevant prior to the 22/23 season; repetition penalties; and fall deductions are also excluded from the calculation of PoM. (Jump sequence adjustments would be factored in if you were calculating PoM for an entire jump pass, however.)

The analysis underlying this ranking takes into account all competitions covered by SkatingScores, the invaluable and fairly comprehensive database of international and domestic competition results. However, SkatingScores is missing some significant Russian domestic events, especially at the novice level. In light of the high number of ultra-cs performed in Russian domestic events from the late 2010s onward, the following events have also been included in this analysis...

All-Russian Competitions taking place in Moscow and St. Petersburg
Russian Novice Nationals
Moscow Novice Championships
St. Petersburg Championships
Winter Spartakiad, Prizes of Santa Claus
Moscow Open Championships, City Championships, Cup, Sports Cup

It is estimated that this analysis, in total, has taken into account over 95% of the ultra-cs that have been attempted in competition since the start of the IJS era, with those attempts missing mainly being from minor domestic events in Russia, in particular minor events outside of Moscow and St. Petersburg, as well as some minor domestic events in Japan and the United States.

Lastly, it should be noted that in the case of any skater who tested positive for performance enhancing drugs, their results are invalidated for purposes of this analysis starting from the season they tested positive, and ending at the point that they were cleared to compete again by the relevant international bodies.

Thanks for reading this and watching! Don’t miss the companion video to this one, which counts down the best quad jumpers of all time, as well as videos counting down the best jumps and jumpers of all time for each quad type and for triple axels.

This channel also features videos for each season, starting with the 22/23 season, counting down the most pristine quads and best quad jumpers, and the best jumps and jumpers for each quad type and for triple axels.
