Litecoin mining - WU compared to Hashrate

I bought a new set of graphics cards for my computer, mainly for gaming but I intend to run them when not at home for extra heat during the winter.

Anyway, I have two sapphire 280x cards. I managed to get them hashing at 750khash pretty easy (2048shaders, 8192TC 256ws 2 thread g2 lg2 i13 1080/1500 - ~75C)

CGminer reports around 1.495mh/s, but a WU of 1364/m. From some searching I found that it is somewhat dependent on variance, but should settle to around 9/10 of total hashrate. Does this sound right? The pool reports 1.3 to 1.5Kh/s most times.

I also have a 7870 running in another rig (1280shaders, 15232tc, 256ws, g1, lg2, 1 thread, i18, 1000/1500 - ~80c)

This pulls 420Kh/s, but my WU is showing as 450/m after running several hours. It's a crazy intensity, but I get no HW errors and my pool recognizes ~420k/s.

Am I mining good and just seeing variance or something? I seem to be getting paid based on my hashrate, so I'm a bit confused on this WU thing...
