Good points, but I also think that a lack of trust is implied. To me it is like political parties... when they don't like the results of polling data, they too frequently criticize or dismiss the pollsters (or their methodologies) and feel further convinced that they can only trust their own data.

So the upside of doing one's own stats is as you've stated.

The downside is that when measuring things that have a subjective element (in hockey, what constitutes a hit or what constitutes a scoring chance) then an inherent bias of favouring one's own can and will sometimes affect one's own results, especially when looking to confirm previously-held beliefs.
