For instance, if Tim Wakefield gives up 5 runs in three straight games it would be considered 3 average-bad starts. However, if he gives up 10 runs in G1, 0 runs in G2, and 5 runs in G3, he actually made 1 great start, one average-bad start, and one terrible start.<BR/><BR/>That being said, it is not really an "issue" but rather it all depends on how you like to evaluate. With my SP-Effectiveness Points system I am more about looking at each individual tree within the forest to properly evaluate a pitcher. You might be more interested in just looking at a season as a whole, which is fine, but just know that there will be things (more than some) that get lost in the equation.<BR/><BR/>End result, though, great math work, great idea, and a barometer much better than ERA.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8980848000817197116.post-15714514135539321232008-01-06T18:01:00.000-08:002008-01-06T18:01:00.000-08:00Thanks SG, I`ll do that as soon as I get a chanceThanks SG, I`ll do that as soon as I get a chanceAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-8980848000817197116.post-249171886205090382008-01-06T18:00:00.000-08:002008-01-06T18:00:00.000-08:00anonymous, yes it does.anonymous, yes it does.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8980848000817197116.post-29864241728731201792008-01-06T15:09:00.000-08:002008-01-06T15:09:00.000-08:00Mike NYY - Very nice.

Also, I have some stats issues I’m working on that I would love some feedback on. I actually have some posted on a website.

I use linear weights as part of my pitching projections when figuring out how many runs we'd expect a pitcher to allow going forward, and I think this includes more useful information than that. You should run a weighted average of the last three years for a few people and see how predictive it ends up being.SGhttps://www.blogger.com/profile/06131200688737789687noreply@blogger.com
