Welcome to the forum.
I strongly suggest reading through the stickies at the top of the forum page. There's a wealth of answers to the many common questions people have. Your question, for example, should go into this thread:
http://forumserver.twoplustwo.com/17...nances-771192/
In all forums, I suggest that you look at the front page at least to see if there is a question similar to yours. When you posted your question, the winrates thread was on the first page too.
You've already got the answers you need, so I'm locking this thread.
