Most likely I'm doing it wrong! I started waiting after I had a sample turn clear, then turn pink again while I was making notes (Just with the 871, still testing for FC). I'm really on day 1.5 of trying to get the hang of this, so I'm learning as I go. I just made an assumption that the pink coming back was a sign I hadn't accounted for all of it. Sounds like my FC is probably much lower than I thought...
