I want to know the tendency of the attacking between two players.

How to calculate?

Formula=(sum of the times of atacks*remaining number of other players)/number of the all attacks

Think about just four players.
Player name A,B,C,D
Think about only attacing tendency of A this time.

At first round A attacked twice B and once C.
Second round A attacked twice B.
Third round he attacked once B and C.
Then B got out.
At this moment A attacked seven times, B was attacked five times. C was attacked twice.
Tendency of attacking from A to B is 5*3/7=2.14
After two rounds, A stored and did nothing,
Next round A attacked once C and killed him.
The tendency from A to C is (2*3+1*2)/8=1
Here A and D remast.
A continued attacking D twice in a round and after three rounds A won the game.
The tendency from A to D is 6*1/14=0.43

How do you see these score?

And to know the long period tendency, set the standard and just sum the difference from the standard.
For exmple, here I roughly set the standard "1"
Then tendencies are (B,C,D)=(+1.14,0,-0.57)

My idea is not based on mathmatics. So please correct (my English,too :/ )and hope to have that kind of index.
