I joined Slush's pool with RPCMiner and saw my account begin to collect a small amount of bitcoins almost immediately (.00009BTC).

The Site showed that I was using Getwork protocol and if I used stratum the fees would be lower.

So I did.

And now, even though I have added workers, my account shows nothing accumulated.

perhaps using stratum makes the jobs bigger and therefore, less updates on the site.  However, stratum is querying stratum.bitcoin.cz on a regular basis. 

Does anyone know of a way to see if stratum is actually making any progress?  perhaps my dabbling with a CPU mining is just not worth it for stratum as the jobs are already old by the time they report back to slush's pool?
