I use Claymore's Dual Ethereum+Decred GPU Miner v1.0 in pool
http://ethpool.orgI see in statistic Effective Hashrate and not see Shares (Invalid / Valid / %)
But miner share found!

It norm?
Read "readme!!!.txt" or OP. Hint:
-esm Ethereum Stratum mode. 0 - eth-proxy mode (dwarpool.com), 1 - qtminer mode (ethpool.org). 0 is default, 1 is useful to get detailed statistics about shares on ethpool.org.
