    Ahh, I see, so you simulated season games and checked the simulated stats versus the player ratings right? I was thinking of doing something similar, and perhaps entering the values in Excel and finding the governing equation just to see how much the different values interact. Good stuff.
    Actually, I didnt have to do anything within the game itself at all at first. I just used Excel on the default roster database and compared the default ratings to
    the season stats from 2002-2003 season that they had already entered. I then hypothesized exactly how I would generate each rating from stats and checked it out. Steals, blocks, assists, rebounds, free throws, and fatigue were easy to figure out because they are derived from very simple stats. Thats seven categories right there. Primacy was a little tougher. I first figured it might come from field goal attempts per minute. But then I remembered that some shots are on a foul that become free throws so I changed it to shots per minute, (FGA + .44*FTA)/MIN, and, lo and behold, although not exactly like EA Sports numbers, they looked quite accurate.

    I now have spreadsheets with ratings tables that'll generate these eight ratings on the fly. All you have to do is enter a couple of stats and theyre automatically calculated. I changed these eight ratings for all the players in Live 2004 and the results looked quite good. Live's roster auto-reordering started actually creating the team's actual lineups without me having to make many manual changes. For fun, I created a couple historical teams too.

    And yeah, stamina was mostly a ghetto-fied way of determining a players minutes it seemed. They need to make a seperate or different way of determining how many minutes a player plays -- it's kind of silly when one of your starters gets injured, and your subs get tired in a couple minutes of play.
    Stamina would be a bit tricky without making a fudge factor. A players actual minutes all depend on the coach, who the team is playing against, and maybe the player's health. Until they have coaches in the game with actual tendencies, the fatigue rating will have to do. It sucks, I know.

      Don't ask me lol, if a player has a 99 pass, and an 80 dribble he'll get like 1 less assist than someone with a 97 pass and 90 dribble, I don't know why it does, but it's how it is.....

      ALso Stamina didn't work well, I'd set a players stamina to 0 and they'd still play 28 minutes when simulating

          What was the difference in turnovers between these two players? That might help explain it.

          That makes sense though. A rating of zero should represent the bare minimum that you'll see in a game, realistically speaking, of course. I've never seen a starter regularly get less than 28 on average.
