##### Need help with formula
« on: September 23, 2021, 10:34:30 AM »
Hello everyone,

I need help creating a formula for our tournament. We play once a week for 12 weeks.
The way the points system work is first player out to rank 11 goes up by one points.
10 to 6 goes up by 2 points. 5 and 4 by 3. 3rd place +5, 2nd +7, 1rst +10.

At the end of the 12 weeks position 16 to 8 in the ranking make final B. The 2 winner of the B join the first 6 rank player to make the final A.

I attach the file we use to determine how many points player gets.

Thank you!

lswitch(r, 10, 7, 5, 3, 3, 2, 2, 2, 2, 2, 1)

Only notable thing here is that everyone ranking higher than 10 gets 1 point.  Your sheet only goes to 20, but in the event there are more players they will also receive 1 point.

Its not exactly that.

The first player out gets 1 points. The player after that gets +1 pts so 2 pts.

So if we are 15 players it goes like this :

1st = 43 pts
2nd = 33 pts
3rd = 26 pts
4 = 21 pts
5 = 18 pts
6 = 15 pts
7 = 13 pts
8 = 11 pts
9 = 9 pts
10 = 7pts
11 = 5 pts
12 = 4pts
13 = 3 pts
14 = 2 pts
15 = 1pts

So its +1 to rank 11. +2 for 10 to 6, +3 for 5 and 4, +5 for third, +7 for second and +10 for first.

Also we're already two weeks into the series. Can I add the points the player already has in the database. I think I say a post before that I have to redo the tournament.

Thank you for taking the time.

Well I made alot of try and this is the formula I came up with

if(rank >= 11, n - r + 1, switch(rank, 1, n - r + 29, 2, n - r + 20, 3, n - r + 14, 4, n - r + 10, 5, n - r + 8, 6, n - r + 6, 7, n - r + 5, 8, n - r + 4, 9, n - r + 3, 10, n - r + 2,))

I'm sure its too long for nothing but it works!
