Lysacek vs Plushenko: A look at the numbers and data

In the wake of Evan Lysacek's gold medal upset in the mens figure skating at the Vancouver Olympics, silver medalist and pre-event favorite Evgeni Plushenko came out and said it: He was robbed.  His contention is that mens skating needs quadruple jumps, and that he did one, Lysacek didn't, and thus he should win.
"We need quadruples ... that is the future of figure skating," Plushenko said. "Without the quadruple, [it's] not men's figure skating. Now it's dancing."
The scoring system in figure skating has changed and is no longer the subjective 6 point scoring system where you had the mysterious "Russian judge" giving scores one couldn't understand, but is now a much more objective, particularly on the technical side, system where each element has a base score and the competitor is judged on how well they performed it.  Further, jumps performed late in the program earn a 10% bonus to give credit for performing them when more difficult and to encourage skaters to not front load their routines making them somewhat boring.  Add this all up and you have the technical score.

Now, a quad jump is indeed given a higher base score and so Plushenko's claim does have some merit, but it is only 1 of 13 elements that are scored, so since I love looking at data, I couldn't help diving in to the detailed scoring of their two routines to see how they stacked up.

In the table below, I've listed the programs for both skaters with the base value for their elements, their grade of execution, and running total along with the difference of their running totals through the programs.  I've also put in bold those jumps that occurred in the second half of the programs and received a 10% bonus for the base value.  Note, since both skaters had identical program components scores, analyzing the technical score is all that is needed to compare them.

From this we can see that Plushenko did take an early lead with his quad/triple combination and extended it with his early triple axel combination and triple loop, but then the lead began to shrink and ultimately became a lead for Lysacek when he threw his triple/double/double combination.  The way the lead varies is really due to the order of the elements as we aren't comparing apples to apples in the rows.  To do that, I've reordered Plushenko's program to match the rows of similar elements of Lysacek's below and the Diff column is the difference for that row/element.  The 10% bonus items still appear in bold.

CCoSp43.51CCoSp43.50.60.4

Now we can more clearly see how they compare.  Looking at just the jumps to start, as expected, Plushenko's quad does give him a big advantage, but Lysacek executed his triple axel better eating into nearly a 3rd of that advantage.  Plushenko got a bit back with his triple axel combination being better executed (even though Lysacek got the 10% bonus here), but the 10% bonus and better execution got Lysacek nearly a point for his triple loop.  They both did a third combination getting the 10% bonus but Lysacek threw in the extra double loop giving him a 0.7 advantage.  But the big difference was Lysacek throwing his triple lutz late in the program got him a 0.6 advantage that he extended to 1.4 with his execution.

In the end, for the jumps, Lysacek had a base value of 58.23 (3.23 from the 10% bonus) and 5.24 for execution for a total of 63.47 to Plushenko's 59.33 base (but only 1.53 from the 10% bonus) and 4.44 for execution for a total of 63.77.  Plushenko's big lead from the quad was nearly completely lost due to poorer execution (0.8 point diff) and not maximizing his 10% bonus (1.7 point diff).  Also, due to doing the quad toe loop, Plushenko wasn't able to fit a triple flip in his program which is more difficult than the triple salchow and triple loop that he did perform.

Lysacek also performed more difficult footwork and spins having a base value of 16.7 with 4.4 for execution to Plushenko's 15.7 and 3.24 for a difference of 2.16.  This results in, from a technical mark standpoint, Plushenko's 3.8 point base point advantage for his quad being lost and Lysacek actually beating him on the technical mark by 1.86.

Now, if Plushenko has simply paid more attention to putting elements where they get more bonus, say moving the triple axel (0.82 bonus) and triple lutz (0.6 bonus), the margin would have been narrowed to 0.44.  That is less than the difference from his poorer execution meaning that ultimately his winning or losing was due to how he arranged his program and his execution, particularly his triple axel where he had -0.36 grade of execution.

So from the data, it does not appear Plushenko was robbed, rather his assertion that the winner needs to try a quad is only one part of the story.

But what do you think?  Do you think Plushenko was robbed?

2010 Vancouver Winter Games - Argh, no CBC!

A week ago or so in anticipation of the start of the 2010 Vancouver Winter Olympics, I wrote a blog entry in which I expressed thanks that I (and those in Seattle or other close to Canada cities that get CBC) would be able to not constrained to the delayed and packaged for Joe American coverage that NBC provided as I'd have access to CBC's coverage which would likely be live and with more detail.  Alas, I was wrong!

I based this on the fact that CBC had covered the 2008 Beijing Summer Games splendidly and I found myself watching them live and just recording and perhaps watching later the NBC coverage.  Unfortunately, it appears that CBC did not win the rights for the Vancouver Olympics, instead CTV did.  Am I'm not the only one that made this assumption and am now disappointed.

So, I'll now be searching for ways to watch events live on the internet, or recording NBC's coverage to watch it at my own pace where I can skip all their fluff.  After all, if they are delaying it for me in the first place, what more harm is there going to be if it is delayed a bit more by me!

Note to NBC, this defeats the whole purpose of your advertising as I skip all the ads when I watch it off the DVR.  If you want me to watch the ads, show it live so I have reason to watch it live and endure the ads.

If anyone has any pointers to alternative ways to view the Olympics on the internet, please comment.

The Vancouver Olympics are 10 days away

The Winter Olympics in Vancouver, BC, Canada are only 10 days away!  It has been only 18 months since the Beijing Olympics, but thanks to the switch in the 90's to have the winter games during the "off" even years, we get to experience all that is the Olympics again.

Unfortunately, something that seems to come up every time the Olympics come around is the subject of drugs and doping.  The constant battle of the testers to catch up with the latest drug or masking technique continues with the cheaters usually being half to a full step ahead although someone usually gets caught and the testers can declare victory.  Given this, I was pleased to see that Italy will fine any athlete caught doping $140K!  All 109 athletes going to the games will have to sign a statement agreeing to pay the fine if caught.  From the story:
CONI president Giovanni Petrucci says the committee has added the deterrent "to show how serious Italian sport is in the fight against doping. Whoever doesn't sign won't go to Vancouver."
Other Olympic Committee's would be well served to follow Italy's example as a further deterent against doping.

But enough about the negative aspects of doping, what about the games and sports themselves?  In the United States, we'll get a steady diet of the glamor sports of figure skating, alpine skiing, speed skating, and hockey, but we'll get helpings of bobsledfreestyle skiing, and unfortunately snow boarding (how this became an Olympic sport I'll never know).  Interested in something else?  Good luck finding it on NBC, but that may actually be a good thing (see below).

For those of us living near the Canadian border, we are lucky enough to get CBC and additional coverage that way, but that could mean just adding curling to the list above!

For the US viewer, there will be a number of interesting stories including:
There will be many more stories I'm sure, and we can depend on NBC to show us as many of them as they show the sports in action.  Which brings us to the television coverage.

It appears that, as was done for Beijing and prior games, NBC will elect to show us plausibly live coverage of all the key events and perhaps more, instead of giving us live coverage.  Sure, a few events may align with the eastern time zone to be shown live there, and the lower tier events NBC doesn't really care about may be live on secondary channels, but much of the coverage won't be live and worse, the events that are live will only be live in the eastern time zone and those of us on the west coast only a few hours from the events themselves, will have to wait 3 hours for all that coverage whether taped or live.

In this day and age of ESPN.com, Twitter, e-mail, Facebook, etc. it is just silly for NBC to think that folks can really hide from the results and thus the drama they are trying to hype will be lost with folks knowing the results.  That alone may cause some to not tune in, but also with so many having DVRs/Tivo/etc. now, if NBC isn't showing it live in the first place, many (I know I will) will simply record NBC's coverage and watch it at our own speed.  Then we can skip the ads and avoid the "up close and personals" which also defeats the purpose of NBC trying to get everything into prime time so they can sell those ads.  Perhaps those of us doing that are in the minority and NBC is really appealing to the average TV viewer who will tune in.

For a longer and more eloquent rant on the subject, see Bruce Jenkins article.

Thankfully, in addition to having a DVR, I will have access to CBC and I expect while they may not have as many total hours of coverage that NBC claims, they will show more events live and I plan to take advantage of that.

What do you think?  What are you looking forward to from these Olympics?  Leave a comment!

Let the games begin!
