Have you tried using the spreadsheet "pivot table" approach to processing the download of the full smallnotes.csv file? Once you get the hang of it you can set up as many filters as you like (say Neverlate, Term, FicoTrend, PaymentsRemain, OriginalNoteAmount, ...) and display a table of individual notes or the max and min discounts, number of notes for sale, etc.). Pivot tables are set up by drag-and-drop and check boxes so they are easy to try out. Couple of hours and you'll be an expert!
