A slightly dirty filter filters better than a brand new one too

 

In my opinion he may be a little anal but not out of line in doing the test. If he had an MY01 with 50K and was doing the test because of the wrong filter .... I would say a little over reacting. Being that he has a MY06 that could be still in its break in period (or close to), I would be curious aswell. Good luck - Makes It New !
