Update: I just received a reward. According to the Binomial Distribution, the odds of me waiting this long without receiving a reward were about .5% - 3% (Probabilities fluctuated as the Network Weight fluctuated) I guess those weren't THAT bad of odds, and I was just unlucky. I would have been more concerned if I reached the .1%-.01% territory, but that didn't happen. To me that would signify that I would have been impractically unlucky to the point that maybe my understanding of the probability of staking is inaccurate. But that hasn't happened so everything is looking reasonable to me.
