Its seems there are a few people that are question the TBF-FLW math out there....
Here is what BassFan.com has to say:

According to Federation representatives who were at the January meetings with BASS, the former, or previous, BASS Federation was down to around 35,000 members as of the end of 2005. If true, that's 10,000 members (or 23%) off the alleged 45,000-strong Federation roster when ESPN bought BASS in 2001.

"Nevertheless, here's some simple math regarding the FLW Outdoors-TBF deal. If you assume that 100% of former BASS Federation members register with FLW (unlikely), and were not already FLW members (unlikely), that's 35,000 x $25 annual membership = $875,000. FLW's $1 million that it's giving TBF annually minus $875,000 in annual membership dues leaves $125,000 as FLW's annual cash contribution under this scenario (note that FLW is contributing more than just cash to the TBF package)."

I think this adds some confusion to what the 80% number is based on...  Is it based on 45,000 or 35,000...
I am guess this number is due to a lot of clubs holding thier dues, my club has only sent in the minimum 6 man roster to state and national to stay in good standing and holding the rest of our dues, to see what happens.  The plot just keeps getting thicker when it comes to the Federation(s)..
