| diff ... TTR difference between players | |
| P(diff) ... winning probability in percent | |
| exact winning chance | |
| P = 1 / (1+10^(diff/150)) | |
| rule of thumb for winning chance | |
| if (diff =< 50) | |
| P = 50 + 4 × (diff ÷ 10) | |
| else | |
| P = 50 + 4 × (50 ÷ 10) + 2 × ((diff - 50) ÷ 10) | |
| P = 50 + 20 + 2 × ((diff - 50) ÷ 10) | |
| P = 70 + 2 × ((diff - 50) ÷ 10) | |
| examples | |
| TTR 1020 vs. 1000 | |
| diff = 20 | |
| 50 + 4 × (20 ÷ 10) = 58 % | |
| TTR 1070 vs. 1000 | |
| diff = 70 | |
| 50 + 4 × (50 ÷ 10) + 2 × ((70-50) ÷ 10) = 74 % |
