.... still remains an interesting statistical question just how different this is from random variation in the different time series over the years. Flip a coin enough times and every now and then you get a lengthy string of heads. Still, entering some rarefied times for the Pirates. No doubt this is all better than the 17.5 games they were behind on July 1, 2001 during PNC Park's first season of use. Nobody ever gave a timeframe for how long was needed for the new stadium to produce a winner.
For the hard core stats geeks out there. Is this a question for a Wald-Wolfowitz test?
