hey the title says it all... deepbit's speed says "292MHs" whilst guiminer says "270mhs" which one is more accurate?

With most pools, your reported hash-rate is based off of shares over time.  GUIMiner reports the 'actual' hash-rate.

If the pool is reporting a higher hash-rate than what your 'actual' hash-rate is, you're getting 'lucky' solving each share.  This is normal variance.

deepbits up to 326Mhs now?? im using a radeon 5850 so 326 is about right... maybe guiminer is wrong?

The Pool doesn`t know your hash rate - the pool simply gets your shares and calculates a hash rate from that.
In case of deepbit it shows you an average speed in the last 10 minutes.
Your mh/s will be stable - but your share rate isn`t because auf stale shares and variance.

This 10 Minutes you`re lucky and it shows more - next 10 minutes your unlucky and the interface shows less.
Like Kermee says.

I was long-perplexed by the same thing in Deepbit. I have about 630 hashing power but it often reported as up to 760 in Deepbit. It made me feel like I was getting away with something  Grin

It means you're solving shares ~10% faster than your card should be, in that timeframe.

You might also see it dip to 550-480 during unlucky streaks, that's normal.
As long as the submitted shares count matches the one displayed by your client everything is working fine

[322.339 MH/s (~291 MH/s)] [Rej: 73/7908 (0%)]

Is the display output from one of my poclbm miners, and the (~ MH) is one of the newer, and my favorite stat that I basically look at as local luck. As I understand it, the first number is how many hashes hashed from the miners point of view. The estimate is a timed based average depending on how many shares have been accepted (maybe + rejected? Not enough to matter it seems). So sometimes its a bit higher than the actual hash rate, and sometimes lower, like now.
These 'lucks' get added up in a pools mining stats, and basically multiplies by how many you have running. If all your miners on a lucky streak, your reported mash rate in the pool stats will be more than your actual.
