If you have specific fields that would help your decision making, please let me know. I thought a great deal about how much is really necessary, but if people can make a great argument I'll consider it. For example, maturity is something that might be important to the user. Same goes for the broad loan grade, as some lenders might further subdivide the picks based on their appetite for the likelihood of default (i.e., some users might wish to employ a mini max strategy where they buy into the idea of the profit maximization but, given that, also want to minimize their risk of defaults by choosing only the higher graded notes).
% funded might not be necessary any longer, as the picks are getting posted so frequently. And I might just remove the "Top" as it's causing confusion; the picks essentially all perform roughly the same in expectation and there's a lot of variance in the 1% notes, so people would probably be better off just randomly choosing among them all. Plus, it would take a long time to build a portfolio of 1% notes. This would give room to put other fields.
Of course, changing the upload file structure is a sort of big deal. Hehe. Lots of scripts to alter, from the statistical script, to the uploader on the web server, to the database tables.
