I am looking forward to the challenge and hope it helps me out, I need lots of help, am not at all worried about the prize or anything, but if you would like to do the percentage thing, I made a spreadsheet I could send you, just PM me your email, all you would do is fill in the name, start weight and finish weight, and it would calculate the percentage, then just sort by column and it will tell you lowest to highest. Let me know.
