Base on your original post, you should find the most efficient player where RUN is the most important factor.

Code:
awk '
max<$2-$3      # Compare recordset efficiency score($2-$3) to max(higher efficiency score) value.
{
max=$2-$3      # If recordset has efficiency score greater that max, assign recordset efficiency score to max.
s=$0           # and assign the recordset to s variable.
}              # Loop until end of file.
END
{print s}      # At the end print the value of s, the recordset having the highest efficiency value.
'  data.file

I don't know but this questions look like a homework to me(check the forum rules).

Pente(6)							   Games Manual 							  Pente(6)

NAME

       pente - Game of five in a row

SYNOPSIS

       pente -help

       pente [ <options> ]

HOW TO PLAY PENTE

       Pente is the American name of a Japanese game called ``ni-nuki'', which is a variant of the ancient game ``go-moku''.  Pente is played on a
       19x19 grid with stones of two different colors.	Each player chooses one set of stones; then the players take turns placing their stones on
       any unoccupied intersection until one player wins.

       There  are two ways to win.  If a player makes five or more stones in a straight line (across, down, or diagonally), then that player wins.
       Or, if a player captures five pairs of his or her opponent's stones, that player also wins.

       Stones may be captured in pairs only.  To capture a pair of stones, a player must place one stone on either side of the pair.

       The first move is placed in the center of the board.  To make up for the advantage of going first, the first player's second move  must	be
       at  least three spaces from their first.  This sounds confusing, so don't worry about it; just play, and if the computer won't let you move
       where you want on your second move, play somewhere farther away.

       That's it!  These directions are pretty terse, but if you have an X display there are better directions available through the ``help'' but-
       ton.  You can also try playing a few games; the rules are simple enough that you can pick them up easily just by playing.

THE PROGRAM

       This program has support for many different display types.  Depending on the compile options used, X Windows, Curses, and a plain text for-
       mat may be available.  The exact display type used will be chosen by the program, or it may be selected with a command line switch.  Infor-
       mation on the switches is available with pente -help.

       Most  of  the command line switches can also be set with the ``setup'' window of the X interface.  Any changes you make there will be saved
       in the .pente.ad file and remembered the next time that you play.

       The command line switches can also be set with an X default.  For example, if you want to set black and white to be the default	mode,  you
       can  run  pente with pente -nocolor, or you can add pente*color: 0 to your X defaults, or you can just turn off color in the ``setup'' win-
       dow.

       Pente will store a new .pente.ad file every time you run it.  In this file it will save the current state of Pente.   This  is  handy;  you
       don't normally have to set command line switches since Pente will remember them in the .pente.ad file.

BUGS

       Sometimes the .pente.ad file gets some bad data in it.  Just delete the file and then you can start from scratch again.
