What does last year's results have to do with this year's standings based on how the two teams have played this year?
You asked for historical data. Hollinger also relies on events that happened many years in the past for curve fitting his play-off predictor equation. Why is his historocal data valid and mine is not?
I don't know if it would have. What we KNOW is
(a) the 76-77 season is integrated into the historical data that went into the creation of the current equation that you're so critical of
Do we know that? How far back does he go. Is what happened 32 years ago statistically relevant to what will happen this year? If he did include it, it's just a single data point, and most likely a statistical outlier.
Again: it's gut-level for you, and it's regression analysis for him. It seems a pretty straightforward thing to integrate playoff experience in his equation if it were statistically significant. Maybe he missed it, or maybe you're wrong.
Or maybe, just maybe, his formula is oversimplistic. And maybe that's why he's constantly revising it. It's not really a "formula", it's simple curve fitting - coming up with an equation that best fits the data. The data changes and he changes his equation.
It would be interesting to create a formula that included play-off experience and past play-off success. I don't have time to do it, but I think it would be a very interesting. Historically, (76-77 Blazers aside), inexperienced teams have not faired very well in the post season. It took the Bulls several years to get past the Celtics and Pistons. You have to go all the way back to the late 1970s to find a "young" team without significant play-off experience that won it all. Once teams figure out how to win in the post season, they are very hard top beat - the Bulls two three-peats, the Lakers three-peat, the Rockets winning back-to-back, the Spurs winning 4 times in 9 years, the Celtics and Lakers pretty much owning the 80s, etc.
Hollinger's equation is fun, but really just how accurate is it. Go back and look at it at any point in the season and see just how closely what he predicts actually happens. At the end of January 2008, he had Indiana with a 66.0% chance of making the play-offs and Philadelphia at 13.8%. Guess who made the play-offs. Of course, the further the season progresses, the more accurate his "predictions" become, but that can be said of almost any system (including simply looking at the current standings).
