I've updated the DaCoinMinster's GreaseMonkey script which tweaks the pool website.
It shows some additional stats and also makes workers' status check even more trivial than it is out of the box.

Now it calculates miner's hashrate and some pool averages properly taking in account different block rewards.

It can be taken here:

Also DaCoinMinster might want to review it and update at userscripts.org?
