Whilst it's possible to do anything with numbers, I'm not sure what benefit would flow from the knowledge of this fairly meaningless statistic.
Something that I have noticed though - and this is based only on my fleeting observations during the four (only) weeks that I have been helping to run the competition, rather than through any scientific analysis - is that when it comes to predicting the fortunes of our own club, we are either morbid pessimists or over-enthusiastic optimists. On first sight it seems that this leads our success rate on predicting City's results to be poorer than it is in relation to other teams. In other words, we seem to know least well that which we are most familiar with.
Perhaps if I have a bit of time I will actually produce some numbers on this.
