Since winning a playoff is the same as winning 4 games, you could give 5/4 (1.25) points for each victory. However, this solution would also give points to the team who did not win the playoff, but won some games.
Another solution would be to calculate these points by hand (which is not so complicated since there are only 4 rounds of playoff), and then to add these points in the Bonus section of each concurrent. The points written in the Bonus text box will be automatically added to the person’s total BEFORE the final ranking is calculated. You will find the Bonus field by clicking on the Edit button beside the competitor’s name in the list of the competitors.
