I hear a bunch of people talking about getting their DC "perfect" so they have very little of even the fine dust in the air, but most of these people do it as a hobby not? It seems like most shops that do it for a living have decent DC but I've also seen many shops with piles of sawdust here and there. So my question is... How important is your DC? Do you just try and keep it from piling up, keep the bulk of it out of the air, or break out the meter and test your system every time you cut a board?
