Defensive ratings are subject to adjustment based upon playing time. Generally these adjustments are simple hard caps based on innings played, but the system for range ratings is significantly more complicated. Since I frequently get questions about the range adjustments I’ve posted a summary here.
Just a general announcement that I’ve started work on the 2010 IBL cardset. I’m going to try to get the defensive range ratings completed and posted to the wiki during the holidays.
In 2005 I implemented a regression algorithm for the LH/RH splits on the cards, replacing the legacy PtP method of basing each side of the card on the raw split data. This is a brief explanation of the rationale and methodology.
