Okay so i see a lot of people discussing efficiency of cg miner and where to watch it. Some say in cg miner other in cg watcher etc.

A lot of people say that WU in cgminer is the best thing to watch efficiency . But my question is, are there any numbers to watch for ?
For example on my 290 rigs WU is 739/mfor one card and 828 for the second, on the 280x its 680/m for all cards but on my 7950s its 600/m.
So are this numbers okay ? How do i calculate what number is okay for each card ? Does it depend on the khs each card is mining ?

Maybe its a noob question but i could not find much info on that matter and i some help will be appreciated,

WU depends on the khs each card is mining. It is "hash/s * luck" according the manual. But i see some strange thing. On 7870 WU is always close to khash. On 290x WU is always less. After few hours it can be 800 khash and 610 WU. I don't think it's right.

Yeah its not the same as the hash rate for sure with my cards.
So i guess the higher the WU the better, but is there a way to work make it better ?
It looks that it does not matter what the intensity is , at least at my rigs.
So is it pretty much only luck or there is actually a way to make it better ?

> So i guess the higher the WU the better
I'm agree.

> a way to work make it better ?
I think via speedup hashrate. And there is something special. May be too high hashrate produces "bad" work and WU goes down... I'm trying to figure it out last week.

> It looks that it does not matter what the intensity is
I don't agree. Do you understand that WU is cumulative statistic for all period since start program? So is right hashrate. But left hashrate is just little averaged for 5-10 seconds and changes fast. If you ran rig for day you need time to change cumulative counters or you need to reset statistic (press d z).
