I don't look at conversions as much as I look at what I'm making per click - if you do 1:200 on a $20 sign up you get 10 cents per click
If you do 1:300 on a $35 sign up you get 11.7 cents per click
As far as my stats, they are for everything that I do, bit I'd bet 90% of the traffic comes from my link list.
