    Ewingandoakley's Statistics Projection Formula and scale

    Ok, I have been doing this for years with MLB 2k, as it helps with the accuracy of rosters. This can help create ratings for anything from a classic season to updated rosters. I usually use it to help create base ratings for guys who either missed a lot of time to injury or only played a fraction of a season, so you can figure out what they would do if they were given a full season.

    The formula itself is:

    162/g=n and after you figure out what n is, you use the formula:

    s*n= The projected statistic in a 162 game season

    Key:

    g= Games Played

    n= Number calculated from the formula 162/g.

    s= whatever statistic you need to find out what it would be in a 162 game season, like plug in 11 if he hit 11 home runs.


    Okay, so now, lets use a real example. In the 2006 season, Gary Sheffield played 39 games because he injured his wrist.

    His stat line was:


    G GS PA AB R H 2B 3B HR RBI SB CS BB SO BA OBP SLG OPS
    39 38 166 151 22 45 5 0 6 25 5 1 13 16 .298 .355 .450 .806

    Usually, I only use it for stats like 2B, HR, RBIs, SBs, BBs, and SOs, because the rest generally do not matter too much when determining a rating. So we start off by plugging 39 into g and dividing 162/39. You will usually get a single digit number under 5 with loads of decimals. In Sheffield's case, n is 4.1538461534615. So lets take his home run total (6), and plug it into s. You multiply s times n and you will get about 25 home runs. Now we are getting somewhere. His home run total in 2005 was 34. His home run total in 2007 was 25. This is a special case because he was injured and he tried to play through his injury. This next step usually doesn't have to be done unless the guy got injured. We can round his home run total up to 30, because that seems like a logical estimate considering he hit 34 home runs in 2005 on the same team in a hitter friendly park, and he hit 25 home runs in a pitcher friendly park in 2007 on a different team. Now, 2k in recent years has made it so that a hitter can only hit around 50 home runs in a simulated season if they have a HR rating in the high 90s. Using that piece of information, I have created a scale to rate home run totals.

    HR Rating
    0-5 40-55
    6-10 56-60
    11-25 61-75
    26-30 76-80
    31-40 81-89
    41-45 90-93
    46-50 94-97
    51+ 98-99

    I have put Gary Sheffield's home run ratings at 79 vs L and 82 vs R.

    You can use similar scales to determine other ratings like SB, BB, SO, and RBIs, and doubles can be rated on the same scale as home runs. From times I have simulated seasons in franchise with (for example) my 2006 roster, where I used this formula all the time, the final statistics are extremely accurate.

    Questions and comments are appreciated.

    Do your home run ratings tend to match up with how many homers they should hit ?

      Yeah, especially if you turn off the injuries. You sometimes have to lower the strikeout tendency and things like that in the player but other than that, a guy who should hit 40 home runs will hit 40 home runs.

        Great thread. I really appreciate seeing some of the effort guys around here put into making these games as realistic as possible.

          Do you have a similar analysis for things like walks and hits?

            Re: Ewingandoakley's Statistics Projection Formula and scale

            walks are pretty easy. The same formula works, just the scale is different. I sometimes like using on base percentage to help out also. Using typical walk stats for the worst walkers, average walkers, and best walkers, you can create a scale.

            These are on full season stats

            Walks Rating
            0-20 40-50
            21-30 50-55
            31-40 56-70
            41-50 70-75
            51-60 76-80
            61-70 81-85
            71-80 86-90
            81-90 91-95
            91+ 96-99

            Hits

            You use the same formula to find out how many hits if he has played regularly and not just as a defensive replacement or a pinch hitter as in the first post, as it works for EVERY single stat that isn't a percentage (not tested yet). But if you want to find out what a player that spent a lot of time as a pinch hitter, there is another formula you need to take into consideration. Lets start with Eric Chavez.

            I have wanted to find out what Eric Chavez would have done given a full season this year considering his success replacing A-Rod. Some of his key stats are 113 games played, 278 at-bats, 78 hits, 12 doubles, 16 homers, and 37 RBIs.

            Okay, lets say that Chavez got 600 at bats, a typical season for a starter. Lets divide 600 by 278. You get 2.15827338129496. Take that and multiply it by 78, the number of hits he got in the season. You get about 168 hits, which if you divide 168 by 600, you will get about .280, within a single point of his batting average for the season.

            These ratings are based on projected stats are for a full season:

            Hits Approx. BA Ratings
            100-110 .166-.183 45-50
            111-120 .183-.200 51-55
            121-130 .200-.217 56-60
            131-140 .217-.234 61-65
            141-150 .234-.250 66-70
            151-160 .250-.267 71-80
            161-170 .267-.283 81-85
            171-180 .283-.300 86-90
            181-200 .300-.333 91-97
            200+ .333+ 98-99

            So the formula for guys like Chavez is:

            600/a=n

            h*n= t

            a= regular at bats
            n= number calculated from the formula
            h= regular hits
            t= calculated hits

            This will work really well.

              What are your scales for the other categories?

              Do you use projection formulas for minor leaguers?

              Do you have a formula for pitching stats?

                  I have scales in my head, but I can't think of them now because I don't have access to my custom rosters right now to verify them.

                  Do you mean as to what they will do in the majors based on their minor league performance, because that might be tough considering how some players react to the majors differently than others. But I can do it and I will work on projection formulas for minor leaguers over the weekend. I will just need to look at minor league player ratings to figure out bases for my scales and formulas. Do you mean as to what they might do in the

                  I will also work on a formula for pitching stats over the weekend.

                    Re: Ewingandoakley's Statistics Projection Formula and scale

                    Ok, I have a pitchers formula.

                    33/g=n

                    Since most starting pitchers pitch about 33 games per year, we will use that instead of 162. So lets take Andy Pettitte's 2012 season to figure out how many wins he would have had if he had not been hit with a line drive.

                    Pettite started 12 games last year, and finished with a 5-4 record.

                    33/12=2.75

                    2.75*5= about 14 wins.

                    2.75*4= about 11 losses.

                    His real winning percentage was .556

                    To figure out his simulated winning percentage, lets add 14 and 11 to get 25.

                    14/25=.56

                    .56 is almost identical to his real winning percentage, proving the formula works.

                    I will develop other parts of pitching stats later, and I will figure out a ratings scale also.

                        had a pretty big discussion with similar ideas a few years back in mk's roster thread.. never got really past contact/power ratings though. its exciting to see people keeping up work on this series even when 2k seems to keep letting us down. if you or anyone has a plan to do a custom roster with these formulas in i'd be glad to help as i plan on doing all the stances and hopefully deliveries this year

                          Are you looking at real stats or just using that formula? How are you formulating your splits? I ask, because Gary Sheffield had a higher batting average and HR% against lefties, yet you gave him a lesser rating.

                          Just curious.

                            I got to wait a few weeks before I can pick it up. It's gonna be tough to do a 2001 roster though because so many guys have retired in the last year that were big back then.

                            It really depends. I look at splits for switch hitters and sometimes regular hitters (if they are platoon players)

                              Thanks for posting this info, this will be helpful when I start rating my roster. How do you determine the ratings for Eye vs Lefties and Righties?
