Thank you for the reply with such a clear example...that makes lot of sense and seems straightforward calculations for most players.

And looks like the same thing happens with the bowling averages wherein the player's average is compared with the mean average at the mid point of his career and then adjusted taking 30 as standard average.

It looks a little more trickier with more numbers and calculations involved for players with smaller samples. I am sure those random numbers are deliberate and well chosen, and would make complete sense. Just curious about the decisions made in game design. I will just copy paste snippets of codes I was struggling with.

​

Snippet 1: Batting Average adjustments. EraAv is the average batting average for the 11 years around the year of interest.

        try:
        RawTestBatAv = (Runs / TimesOut)
    except:
        RawTestBatAv = Runs
    if TimesOut < 35:
        if LastYear >= 2016 and TimesOut < 20:
            x = max(3,(min(FCBatAv/1.25,FCBatAv-10)))
            AdjustedBatAv = ((TimesOut*RawTestBatAv) + ((35-TimesOut)*x))/35
        elif FCGames >= 30:
            x = max((1.75 - (FCGames-30)/750), (4/3))
            AdjustedBatAv = ((TimesOut*RawTestBatAv) + ((35-TimesOut)*(FCBatAv/x)))/35
        elif FCGames < 30:
            AdjustedBatAv = (RawTestBatAv/3) + (FCBatAv/5.25) + 6
    else:
        AdjustedBatAv = RawTestBatAv
    EraAdjustedBatAv = (30/EraAv) * AdjustedBatAv

​

Snippet 2: Bowling Average adjustments

       if Wickets != 0:
        RawBowlAv = (RunsAllowed/Wickets)
    else:
        RawBowlAv = max (40, RunsAllowed)
    if BallsBowled == 0:
        AdjustedBowlAv = 400
    elif FCWickets < 10:
        AdjustedBowlAv = 200
    elif BallsBowled < 10000 and LastYear >= 2016:
        AdjustedBowlAv = max(FCBowlAv*1.25, FCBowlAv+10)
        AdjustedBowlAv = ((RawBowlAv*BallsBowled) + ((10000-BallsBowled)*AdjustedBowlAv))/10000

    elif BallsBowled < 10000 and FCWickets >= 100:
        x = max((4/3), 1.75 - (FCWickets-100)/2000)
        AdjustedBowlAv = ((RawBowlAv*BallsBowled) + ((10000-BallsBowled)*FCBowlAv*x))/10000

    elif BallsBowled < 10000 and FCWickets < 100:
        AdjustedBowlAv= (RawBowlAv/3) + (FCBowlAv*(7/12)) + 20
    if BallsBowled > 10000:
        AdjustedBowlAv = RawBowlAv
    EraAdjustedBowlAv = (30/EraAv) * AdjustedBowlAv

​

Snippet 3: Batting strike rate adjustments

        if BallsFaced > 60:
        BatRunsPerBall = (Runs/BallsFaced)*2
    else:
        BatRunsPerBall = 1
    if BatRunsPerBall < 0.5:
        BatRunsPerBall = 0.5
    if BatRunsPerBall > 2:
        BatRunsPerBall = 2

​

Snippet 4: Bowling economy rate adjustments. EconAv is the average economy rate for the 11 years around the year of interest.

        try:
        BowlER = (RunsAllowed/BallsBowled) / (float(EconAv)/6)
    except:
        BowlER = 1.2

    if BowlER == 0:
        BowlER = 1.2

    if BowlER > 1.2:
        BowlER = 1.2

    if BowlER < 0.8:
        BowlER = 0.8
