Default How do you guys get such precise gravity readings?

I've got a nice hydrometer (finally after batch 5!), but it's in 2/10th increments (which I believe is the same as all of them). A very 'analog' (non digital) device. So how are you getting it to the 3rd value to the right of the decimel? I.E. 1.08x or 1.02x

My hydrometer is graded in .00x decimals. But hell, .001 doesn't make a huge difference.

Is it digital? Because I don't see how some lines could get to that level of accuracy. Not to mention the water line (or 'beer line') is kind of fat, enough to cover 1/10 give or take of the measuring line. But I'm new to this and still working a million things out...

If it is on the line it is even, if it is in between the lines it is odd. Thats how you get .001 accuracy with it only having every .002 lines. if it was every .001 lines, you would have .0005 accuracy.

C02 is heavier than air so there will be a cushion but theres still a chance of oxidation. Personally i'd rather not risk it. Also, if you're taking the sample with a wine thief, you would be getting a sample from all the strata and it would get mixed when you put it in your hydro tube, so it should be pretty accurate even without stirring.

I'm fairly casual about my brewing aside from sanitation. When it comes to oxidizing my beer...I tend to not worry. I've shaken fermentors, splashed fully fermented beer, etc. I've never had an oxidized beer in the years that I've been brewing. Some of my beers have been in my cellar for well over a year, they still taste great. So...maybe I take the RDWHAHB saying a bit too far, but until I have some serious problems, I'll continue in my slacker ways.
