Win percentage
The win percentage is a weighted average of the outcomes of all your matches, with weights taken
to be the size of the scenario played in the matches.
Suppose you have played n matches, in the formula below, i ranges from
1 to n.
| win i=1..n matches
|
function |
win = | |
∑i=1..n
[
size(i).outcome(i) ]
| |
∑i=1..n
[
size(i) ]
|

Recursive version of the formula
Define : wn - 1
and zn - 1
the win percent and sum of scenario size up to step n - 1 ;
o and z the outcome and scenario size of the new match. Then at step n the win
percentage is equal to :
wn
= | |
zn - 1
wn - 1
+ o z
| |
zn - 1
+ z
