Matthew:
I don’t know how you calculate the collective2 rating. What I found is all my systems at C2 share the same rating of 9.62 although one is still losing money. 
–Dave
Ratings are calculated on a per-trader basis. The idea is that we want to prevent someone from creating a hundred systems, hoping that one will randomly work out… and then advertising his C2 rating for that one good system!
That your rating is good despite the fact that you have one losing system is a testament to your other systems. I will be releasing more information about how the C2 rating is calculated soon. (The algorithm will be tweaked over the next few weeks, to make results more meaningful for shoppers of trading systems.)
