Well, well... Similar experience, other pool: suprnova.cc
I just mined ZEN on Suprnova 58109.22 h/s for 24 hours...
Result: 6.24 ZEN earned Expected results: 7.86 ZEN earnings (source : whattomine)
I know about the luck factor, but -20.6% is not bad luck anymore, neither PPLNS reward scheme...
Moreover, this is not the first time I notice this on Suprnova pool, but this time I wanted measures straight! Sorry, I did stoploss and did not wait for a week... Conclusion: STAY AWAY from Suprnova as well!!!
Any idea on a reliable and honnest ZEN pool ?
