I typically brew the max amount of beer when I do, and so it's not too far from the top. I add .001 for meniscus, which seems rather close, though it could easily be .0005 off, and even if it's merely .001 off do I care enough? I try not to and just know I made beer.
I've read of some people using the plastic tube that the hydrometer comes in, but they sell slightly larger testing tubes also. I have one, but don't use it unless I'm brewing a small test batch where the hydrometer can't get a reading as it's too shallow.
I broke my original hydrometers, and they were zeroed at something like 62-64*F. My new ones are zeroed at 68*, which I prefer as that's closer to the temp I'll get it down to prior to pitching yeast, and if nothing else only need to add .001.
