100% this. It's actually really hard to shoot a moving target that is aware they're being shot at and is doing their damnedest not to be shot.

I think part of problem here is that when most people hear the word dodging they're thinking of something along the lines of a boxer juking out of the way of a punch. In GURPS you're only dodging like that if you do a dodge and step, acrobatic dodge or a dodge and drop, otherwise it's just you basically flinching at just the right moment to be a hard target to line up with.
