The o-ring makes a great edge to guide the sharpie. Just make sure the o-ring is relatively straight/level.
To "set" the volume, I put a measured amount of water in (a couple gallons I think) and drained it completely. The difference between what went in and what came out is the "dead" space. I left that in and started filling a quart at a time. It was about 2 gallons before it even appeared in my site glass. So my first marked "even" gallon is 3.
To measure dough-in water, you have to make sure you heat enough that you will be able to measure the last of it or add the exact amount needed and completely drain the hlt.
