.... lol.
I meant to ask if they hit resist on you more often, as I'm not sure if resist is related to your psy or int values (haven't really checked). Not the other way around.
How much accuracy equals your 280 dex? You may have more accuracy enhancers, cranking up your accuracy more than it would for someone with high dex, but no accuracy boost.
Also, what class are you? Reason I ask, is maybe it's related to the class and/or weapon one wields as well, because I miss a lot less when using a dagger than when using a mace for example... (and no, the dagger doesn't have dex/accuracy).
