This might be a stupid question, but my preliminary search results haven't borne any fruit. Do you round up or down in Shadowrun? The two mentions of rounding in the SR4A core rulebook say "rounding up," but I'm unfamiliar with a generalized rule. And the results I've found for searching are about essence rounding, whereas I'm specifically interested in the glitch point for odd dice pools. For instance -- if your dice pool is seven, do you glitch on a three or a four?
I lean towards rounding up, but I'm not sure if I've missed a sentence somewhere or not.
