You'll get more "Stratum has detected new block on pool 0" than you will accepted shares. WDC and DGC to not deliver close to what coinwarz says you'll get due to the short block time.
For sure. Thats what they added the new column for, in CoinChoose. I noticed it much more with WDC. Once Vern fixed Stratum on Digicoinpool.com, the estimates have been pretty close, with DGC. Within 90%, I'd say.
