AGI Broken?

[Estu]

Abacab told me on IRC that Agility in P99 doesn't work the way it should. Granted, dude's been banned for eons, but I was wondering if anyone can confirm or deny this. His basic assertion was that AGI is supposed to improve your avoidance (so, you're supposed to get hit less often) but instead only improves your AC and doesn't affect avoidance. I'm not currently leveling any melee characters but I might twink one up when I hit 50 and get some dough, so I'm interested in this issue for the future.
