March 29, 2011 BP UnfilteredComparables and UpsideWe've just rolled out some updates to the player cards:
We've also made some progress on the remaining components of the projections:
While we're on the subject of the Fantasy product, I wanted to clear up something we've been seeing in comment threads and email and plainly haven't been doing a good job of communicating. We have not released a PECOTA Weighted Means Spreadsheet since the the initial release. In previous seasons, we'd run PECOTA updates during the preseason either to add players whom we hadn't projected originally (such as a fringe minor leaguer going bananas in spring training and pushing his way into the picture on the major-league team) or because we were tinkering with the settings. The former was a requirement only when we were running in Excel—in the last couple of seasons, we've simply generated projections for everyone (roughly 6000 projections per year). As for the latter, we haven't touched PECOTA's inner workings since we released the original WMS. We decided not to include the projected playing time in the WMS this year for a couple of reasons. First, it wasn't there originally, and we heard from people who were confused when we added it. Second, we had a lot of higher-priority issues to work on, so we decided to add a button in the PFM that subscribers could click to download all of the data in CSV or TAB format. Our intention was that users who wanted the playing-time-projected numbers could download them there at any time. We've changed around virtually all of the other statistical processes on the site, and we've been squashing some bugs as we've found them in some of the fantasy products. For example, we recently had too many wins listed for Seattle pitchers on the depth charts and in the PFM. We've resolved most of those issues, and we've also added checks to ensure that they don't re-occur wherever we've been able to do so. We're aware of the issue with Trevor Hoffman's 2007 WARP scores not matching in the "Standard" and "Recent Performance" tables on his player card, and we'll be addressing that shortly. Thanks again for your continued patience. More is coming soon.

Dave - thanks for the updates. Maybe you can explain how Travis Snider get a 0% chance at breaking out? With his age and previous playing time limitations, wouldn't he be a prime candidate at breaking out? If PECOTA said 2%, I wouldn't have thoughotu much about it, but 0% just doesn't smell right.
Why is this question never answered by one of the authors? Its like they KNOW something is screwed up with the Improve/Breakout rates, it won't be fixed, and they are sweeping it under the rug.
I'll get an answer on this.
