My 2 cents... All hits recieved are the natural flow of money unless someone gives a note to someone for no other reason than to obtain a hit (IE exchange notes). I have never done this and no tracker I know has ever done this. As far as I am concerned there can be no bogus hits as long as a person obtained the note they hit doing regualar spending. When I give someone change ( break a larger note) if the note I get is marked I will enter it and if the person I give change to enters one or more of my notes I consider them valid hits and when and if they get hit again I know that it was a note that was hit by the person I gave change to. A hit is a hit is a hit and I am interested in all of them, because it is interesting to see where the note travels and all hits are part of it's travels. The hits that interest me the most are multiple hits on one note and long life, but those are few and far between..
The fact that I joined this site has disrupted the normal flow of money for me, because before I joined this site less of my spending was with cash. I now make more cash purchases in order to see where the notes will go...
This is at least 2 cents worth so I will cease and desist.

HAPPY TRACKING TO ONE AND ALL
