Question about FFR Rank

[XBmaster]

I just recently decided to go through and play all of the songs I could to try and get my overall rank up, but it seems like it should be higher.

I'm currently at around 22,000. The only reason I think it should be lower is that because all but a few of my scores are ranked under 16,000 and the majority are under 10,000. (I'm using FFR - Level Rank Stats for this info)

I'm not sure how exactly the rank is calculated and it seems like I'm missing something, so that's why I posted on the newbie forum.

Any light you can shed on the rank or why it works out this way would be appreciated.

Thanks

Noah


EDIT:

I just thought of something. Are Credits, Games Played, and Multiplayer level used in FFR Rank calculations, or is it just Your Grand Total?
