Not to sound like an ass or anything, but the top 20 or so JV partners are actually the only one's that really matter.
I just did a launch that made $1,100,000 and we had 400 partners. The top 10 guys did 70% of the sales, the top 20 did 87%. 380 JV's did 13% of the sales. Who am I going to focus my attention on? The 80/20 rule applies to almost everything.
