What is this "credit" you speak of? I don't think anyone else considers download stat as "credit" in the conventional sense.
Anyway, yes, please do list the torrents that you have received "credit" for downloading... Also, I don't think anything you have downloaded is normally freeleech. BTW, just in case you still haven't caught on, the current site-wide freeleech is temporary and only for the holidays. Anything you have downloaded before this started (about a week from the end of December) would have been subject to normal freeleech rules.
And one more thing, what you think is "no ratio" is a green infinity sign. Look more carefully.
