Romario - Having mined Z classic myself, I can tell you that even the honest pools do not deliver anywhere near what the calcs say you should receive.  To me, those theoretical yields from places like, whattomine.com, which are normally pretty good, those figures are way higher than what Z cash classic actually yields.  You get about half or less of what you are supposed to get, despite a low 1% pool fee.  Two thoughts, one, thank you to ZPool for not wasting anyone's time with that crypto.  Two, I think this luck factor Jared is referring too, explains this discrepancy I've been seeing first hand, which I do not see with any other coin.  Even a good friend of mine hosted his own Z classic pool, and no one was getting the numbers they were supposed to be getting.  The huge discrepancy couldn't be explained by the PPNLS system either.  Personally, I believe there is a built in problem with the algo.  Perhaps this "luck" factor IS the very problem?

Anyway, I'm no math/crypto expert, just a victim of that discrepancy at even the first grade math level. I hate to see anyone else fall victim to it and the "unofficial" announcement of a fork, that might or might not happen, depending upon whether the pump and dump is successful...  And yes... I was mining it at $4 last month... 10 days later... it was at $10 bucks.... next morning with a mouth full of lucky charms, I watched it go to $80.... and I sold that evening at $119.  Point is, buy your ZCL and ride the wave... but don't mine it... you'll get 40-50% of what you should.

Thought I'd add my 2 cents worth.  Don't waste your time with ZCL... or at least cut your estimates in half so you are in the real ballpark of what your yield will really be.  That's been my experience.
