Hello, my name is Gabriella Labrest and I work for Decision Technology.
I'm a sports analyst.
We decided to look into the home advantage, partly because of looking at Greece and Australia's performance in the recent Olympics, but also because everybody's interested to see how Team GB will be doing in Rio 2016.
As soon as a country is awarded the Olympics, they start to pump funding into sports.
And this means that they have athletes that are better prepared and better funded, have better equipment and therefore have a better chance of doing well.
Additionally, there's a home advantage effect.
The home Olympics is really going to be the peak of a nation's performance.
We wanted to see what the rate of decay was after the Olympics and to see if, after the Olympics, these teams were dropping off faster than they should have been or if, in fact, they were doing better and managing to maintain that Olympic glow that little bit longer.
So what this involves is looking at the time from when they held an Olympics and games afterwards and trying to fit an exponential function to it.
And then we can compare the different rates.
What this gives us is a total medal decay rate and additionally a gold medal decay rate.
And then you can compare how different countries have performed after their Olympics.
The standout appalling performance has been Greece since Athens 2004.
They have a decay rate of minus 1.04, which is double the largest of any of the previous medal decay rates.
They've really fallen through the floor.
There's no other way to describe it.
The interesting thing is when you look at Australia, because the Australian media got very upset over the summer about perceived poor performance.
And the answer is that in terms of total medals, they haven't done that much worse than we would expect.
It's perfectly in line with the average decay rate.
However, in gold medals, they're slightly below.
