I feel the 5% and 10% number is an absolute number so whether that number of affected donors donate at the beginning, middle, or end of the donation period should not matter.Either way, at the end of the day, 5% are disqualified and 10% are not detected.Thanks. gixxer1000 Director Joined: 26 Jul 2007 Posts: 541 Schools: Stern, McCombs, Marshall, Wharton Followers: 5 Kudos [?]:
