PKSCORE
PKSCORE PLAYERKILLING
1
A players pkscore is based on the players kills and deaths as well as the
players status rating. All of these numbers can be found on the players
scoresheet (type score). For those interested in the formula, it is listed
below. Besides being something to brag about, the 10 players with the
highest pkscore are listed on the top 10 for best PK'ers (type top10).

    D = deaths, K = Kills, S = Status

  PKScore = 10 * sqrt(S) * K * (K^2 - D^2)/(K + D)^2;

If you use this formula, do remember that the MUD does some rounding up
and down due to handling all these numbers as integers.
