Oh, I can be wrong, I make mistakes all the time. I'm not perfect. I was so adamant that CF didn't make a difference because I remember struggling to find a use for it, performance-wise, 3 years ago. Back then, I didn't have the experience I have now, so I didn't know how to do it. Now I know, and I realise it does make a difference. Sometimes backtracking is a good thing - opens your eyes. So I suppose I have something to thank you for.
