In other words, a lefty hitter who batted .280 overall would be rated to hit about .287 against righties and .267 against lefties. If that player faces righties about 2/3 of the time, his overall average in his DMB games would be around .280. Similar adjustments are made for right-handed batters and for pitchers." David

I'm going to play around with some of the tools that gp sent me and see what they could do to reduce my workload. It's hard to justify doing something for free if it starts taking time from my writing for a larger audience or the small consulting jobs I do.
I definitely understand that and again think it's great you continue to do so. I wasn't knocking you or you disk just commenting. I was all ready to use it for our season when DMB decided to change the release date of it's disk which made me and a lot of others extremely happy.
