Still, it's a bit dismaying how many regularly bad teams continue to be bad -- or even worse -- even those you'd think could hardly get any worse. Right now, Cha is headed for 13-53, Det the same, GS 19-47, NJ 12-54, Sac 17-49, Was 8-58 !

At the quarterpole it might be nice to see more detail, i.e. the actual / pyth. projected win totals for the teams alongside the contestant projections and / or team by team variances between these two win figures for each contestant.

Pyth+ is team's current wins + (Pythagorean W%) *(remaining games)
For 17 of 30 teams, we have all guessed too high or too low, and this is shown. As games are won and lost, these lines affect the magnitude, but not the ranking, of the predictions.
For the 13 other teams, where pyth+ is within the range of predictions, every game won or lost changes the average errors' ranking in the bottom line.

So what you're telling us is that you're stoked? Are you from Northern California by any chance?

Dude, you're right at the average.
But just like every year, it's amazing how little we can improve on just repeating the previous year's pythagorean W%. That 'prediction' would be next-to-last among our entries, and none of us are more than 1.3 wins closer to the mark than that.

While most of us have successfully predicted a few major advances and a few major declines, these are mostly offset by teams which should have gotten better but didn't; and others which should decline but just refuse to cooperate.

Predictions based strictly on a 'system' don't seem to fare any better than those based on gut feelings; but I suspect there's great advantage in having an inside track on developments like: who is showing up out of shape, who has been able to perfect some moves, etc.

In other words, there's no shame in losing to Hollinger here.

Update: errors up for almost everyone; now ranging from 6.33 to 8.11

This is one of the reasons whenever someone criticizes JH, I take issue with it. Dude knows what he's doing when it comes to this kind of stuff. Whether it's pure smarts or having the resources or whatever. Respect.
