I seriously doubt it is hop creep
Probably right, but I would raise the temp back up to at least 73 anyway. If hop creep, it will help. If not hop creep, then it's not finished, and higher temp will help. It's too late to get off flavors from raising to 73.
What would lead you to conclude it's not finished?
It dropped from 1.012 to 1.011. Until it stops dropping, I figure it's not finished. Actually, if hop creep is responsible, it's still not finished.
That is well within the margin of measurement error. Virtually meaningless.
It's not much difference, I agree. I might be overconfident about accuracy since I use a narrow range bottling hydrometer. But I believe a standard hydrometer can pick up that difference, when strictly comparing two samples, given the same person reading it and the same beer being measured, and the person is skilled at taking the readings. But I'll grant that it may be a stretch. If there's been no change in gravity, my comment is totally irrelevant.
a couple bubbles on the hydrometer can make that kind of difference. Not to mention eyesight. I don't consider 1 point to be a difference.
Denny - I don't mean to be argumentative, but I feel that I should share my experience with gravity samples. I take a sample 3 days before bottling day. Then on bottling day I take a sample. With the temperature correction, they are normally within .0003 or less of being the same. I do use a narrow range bottling hydrometer, so that helps with reading the hydrometer. But it gives me confidence that the sampling, handling, and degassing can be done repeatably. Eyesight is another story. I absolutely don't trust my readings to be accurate to that degree, but I do trust them to be repeatable.
