I will be glad to send you an email with projections for previous seasons.

]]>This statement seems ridiculous to me. If you have x – y = z where x is year 1 performance and y is year 2 performance and you know the error range for a single years performances is +-10 then the error range for z is going to be +-20. If you instead use multiple years, and adjust for aging to try and more closely have x represent true talent and you are successful so that your error range of x is decreased to +-5, then the error range of z is going to be +-15. The actual mean error will depend on the distribution curves for each equation, but you should end up with a mean error of the 2nd example being about 75% of the first. That you did not is not a result of “the increased accuracy being masked by the noise inherent in a single season measurement”. It is a result a result of the particular manipulations that you performed to give you your projection having failed to provide you with any better predictor than the previous year’s stats.

]]>When will we get park factored wOBA (the one used on this site that includes baserunning etc) on the projection page? This information could be useful.
