Good Morning ,
yes its true , there is an very high Orphan Rate right now .
I checked everyting twice an there is only one Solution .
I noticed that Suprnova got high Orphans if Pool was low on Hashrate opposite NetHash. Now Suprnova Pool has lots of more Hashrate and Orphans gone .
Thats the Same here now on my Pool , low Pool Hash opposite high Nethash = Orphans .
Keep in Mind that eMark is an POW/POS Coin. POS Blocks count for Orphans too.
Solution : More Hash Power is needed to equal Pools
