I know the commonly shared advice is to take gravity readings when you think fermentation is done, and when you get 3 days of the same gravity reading, it's done and you can cold crash, keg, whatever. But this is advice based on taking a gravity sample once a day. With the Tilt, you obviously have access to a lot more data, with samples coming every 15 minutes. So you can see the whole trend and understand a lot better when the gravity trend has flattened out.
Given the very slow rate of change of gravity when you get toward the end of fermentation, I would agree that if you're just taking data samples once a day, you could fool yourself thinking you're done when maybe it has a bit more to go. So the 3 days of samples reading the same makes sense.
For those of you using Tilts, do you consider fermentation done once you see the gravity has bottomed out, or do you wait until you see it bottom out and then wait 72 hours?
Initially I thought I didn't need to wait 3 days like all those suckers that don't have a Tilt. But lately I've been wondering if there's some "post gravity drop clean up" I'd be missing out on by cold crashing too soon.
