New Methods for Analyzing a Tennis Match

Everybody is fellating the Stanford kid, but this guy's contributions to data analysis in tennis, in my estimation, are more groundbreaking and potentially useful.
His Blog:
Game, Set, Map

Traditional methods for summarizing tennis matches have long ignored the spatio-temporal component of the match, and often fail to geovisualize patterns by way of map or graphic. This paper presents alternative approaches to post-match analysis using geospatial data analysis with a Geographical Information System (GIS). A case study focusing on the spatial variation of serving from the London Olympics Gold Medal match, where Andy Murray defeated Roger Federer 6-2, 6-1, 6-4, is conducted. By mapping the relationship between space and time, we were able to visually and statistically quantify that Federer served with more spatial variation during the match. Murray, however, served with greater spatial variation at key points during the match. Results suggest that there is potential to better understand players serve tendencies using spatio-temporal analysis. The importance of such analysis for coaches, players, fans and the media to further explore player tactics and strategies are discussed

Badass analysis

I'm going to read this when I get home. Looks really interesting

So basically the guy is a cartographer and a tennis junkie. He's charting the physical physical location of every single shot in every single point during a tennis match, and with that data he's creating graphs that illustrate clear tendencies of players and how well they do when they resort to those tendencies.
His system is still in its infancy right now,* but once he is able to easily get this data for every match, the practicality of that information is huge. Top pros will definitely be hiring this guy as a consultant in the future.
*I'll get to that in a second.
To be able to graphically show Andy Murray, for example, that: "if you hit your first serve on the ad side to Federer's backhand, he is going to return cross court 75% of the time, and it's gong to land three inches behind the service line, and if you hit the next shot back up the line, you should win the point 87% of the time", would probably elicit a response from Andy like "oh man, I think it just moved".
So right now, this guy is getting his data from software that he has that analyzes the video of the match and breaks down each individual shot. But every match isn't on tv, and even the ones hat are on tv aren't gonna give you a a constant camera angle, which I presume the software needs.
And so that's why his blog at this point is limited to breaking down just one match.
What he's trying to do is get the hawk-eye people to give up their data. This would completely obviate his existing system of video capture and software analysis of the same.
The bastards won't give him the hawk-eye data
But nobody wants to claim ownership of that data. And nobody is willing to hand it over. Eventually, I think they will. Either way, I think what he's done without the use of the hawk-eye is really really impressive.

The team running the Swiss Indoors tournament in Basel granted me permission to all of their match data for their 2012 tournament. I was ecstatic. Finally I would be able to grow my research, and potentially help some of the pending requests from other interested parties. However, they didn’t have the Hawk-Eye data in-house (sigh). I was then directed to Hawk-Eye themselves to retrieve the data
A further six long months has passed and I am yet to see any sight of the data from Hawk-Eye. Apparently they are too busy to attend to the request of the Swiss Indoors to release the data (grrrggh!).
But nobody wants to claim ownership of that data. And nobody is willing to hand it over. Eventually, I think they will. Either way, I think what he's done without the use of the hawk-eye is really really impressive.

Has a thread ever actually been ended by the above? And I mean, like in the history of message boards?
