Average hashrate on cgminer lower than current hashrate?

[Spetznaaz]

I was wondering if someone may be able to help me.

So my current hashrate on cgminer is stable at 780Kh/s. The average hashrate, which if i'm correct is the one next to it, is much lower and jumps about a bit.. e.g 780K/757Kh/s

It's really bugging me as it makes no sense, surely it should be the other way round?
