400MH/s+ on a 5850?

So GUIminer is saying I have broke through 400MH/sec on my 5850.

What do you guys think? Is this just a bug/quirk in the way guiminer updates the hashrate when multiple miners are running, or have I found a way to squeeze out an average of 400 MH/sec from a 5850 without a massively insane overclock? It runs stable if i dont try to move anything on screen Wink

My GPU settings are
-5870 Bios
-960 clock
-300 RAM
-1.162 Vc

I set up three phoenix instances. The first instance I set to

-k phatk DEVICE=0 VECTORS BFI_INT WORKSIZE=256 AGGRESSION=13  FASTLOOP=false
that worker was set with CPU affinity to use both CPU cores

Second instance:
-k phatk DEVICE=0 VECTORS BFI_INT WORKSIZE=256 AGGRESSION=8  FASTLOOP=false
that worker was set with CPU affinity to use CPU core #1

Third instance:
-k phatk DEVICE=0 VECTORS BFI_INT WORKSIZE=256 AGGRESSION=8  FASTLOOP=false
that worker was set with CPU affinity to use CPU core #2

When running, the MH/sec goes as low as 386 and as high as 412, but seems to average out at about 402 to 404

A screen grab of guiminer in operation, along with GPU-Z and Afterburner settings is here

This might seem like a cock length post, but i promise its not. I just want to know if this is a true hashrate or if GUIMiner has some kind of weirdness in calculating hashrates when multiple miners are running and hoped someone here would know.
