Ah, with you now. Without wanting to give a free lesson on statistics (again) Quins result must be included in an analysis of the financial results of SL clubs. Why would they not be? Just because the number looks a bit different to most of the others does not mean it should not be included, it falls within the boundary that any statistician would consider "normal" for the results provided.
Their results might be an "obvious anomaly" to you, but in fact they're not.

Why would he do that? In the same way that no sane person would include Quins 2009 performance when illustrating an average for the other clubs.
In his defence, Mullan hasn't tried to reinvent statistics to prove some kind of absurd and meaningless point. On the face of it there is nothing wrong with his comparison of Rovers results against Saints, however as you point out, the choice of Saints as a comparison is questionable. It could (and does) at first glance make Rovers results appear better than they are.
Why he would chose to do that is for him to answer. I couldn't say, I wouldn't have done that. It doesn't say anything about Rovers financial performance, which is what the article is supposed to be about.

Statistics and accountancy (as Mrs B is now aware) are two very different things.
