    For anyone here has ever written a simulator....

    For any particular pitcher vs batter matchup, how did you split the statistics between the two for your outcome probability? 50-50?

    Wow, I shoulda just did a little google work. And my instincts were correct:

    Assuming a .260 league average, the .290 pitcher is worse than average. Therefore, the batter should hit for a higher average against this pitcher than his overall average.

    I used James' formula on 5 different variables. Line Drives %, GB%, FB%, BB%, K% and previously where they added up to 1, they are now adding up to .973 after using his formula. Not sure what I did wrong.

    Hitter:
    LD% - .2144
    GB% - .3103
    FB% - .2553
    BB% - .0782
    K% - .142

    Totals 1.0002


    Pitcher
    LD% - .1591
    GB% - .2095
    FB% - .3268
    BB% - .0828
    K% - .2218

    Totals 1.0000

    Using James Formula (Batter * Pitcher * / League) / B*P/L + ((1-B)*(1-P)/(1-L) is coming up with:

    LD% - .2271
    GB% - .1975
    FB% - .3070
    BB% - .0799
    K% - .1612

    .9727


    Thoughts?

    Nevermind, I found it. One of my league average numbers was off a little. I now got 1.0069 and 1.0035 with another matchup. Good enough .
