Points per player (calculate)

[schummi]

Hi, i try to do the formula to my rank but i wasn't succeed

this is how to calculate the formula:
last player to 31º place: add 1 point (player per player) (example: 35 players - 35º won 1 point / 34º = 2 points / 33º = 3 points / 32º = 4 points / 31º =5 points)
30º to 21º +3 points (continuing exemple above (35 players) 30º [5+3] = 8 points / 29º [8+3] = 11 points / 28º = 14 points ... to ... 21º = 35 points
20º to 11º +6 points (continuing exemple above (35 players) 20º [35+6] = 41 points / 19º [41+6] = 47 points / 18º = 53 points ... to 11º = 95 points
10º to 4º +10 points (continuing exemple above (35 players) 10º [95+10] = 105 points / 9º [105+10] = 115 points ... to ... 4º = 165 points
3º +20 points (continuing exemple above (35 players) 3º [165+20] = 185
2º +30 points (continuing exemple above (35 players) 2º [185+30] = 215
1º +50 points (continuing exemple above (35 players) 1º [215+50] = 265

i will waiting the answer

Tks

(n-r+1) + if(r <= 30, (31-r)*2) + if(r <= 20, (21-r)*3) + if(r <= 10, (11-r)*4) + switch(r, 3, 10, 2, 30, 1, 70)
