Canterbury Open 2020 has finished. You can find the results here.
Also, I’ve calculated the improvement score for each player. Please see the previous post to become familiar with it. The results are in the table below. You can find a more detailed report in Comments.
| 1 | Ullah,Sami | 0.26 | u1600 =2nd |
| 2 | Allison,Brian C | 0.24 | u1800 1st |
| 3 | Ng,Clive | 0.19 | Open 2nd |
| 4 | Monir,Arman | 0.12 | |
| 5 | Gergis,Steven | 0.11 | |
| 6 | Dragalchuk,Vladislav | 0.09 | Open 3rd |
| 7 | Dib,Michel | 0.06 | u1600 1st |
| 8 | Fernandez,Daniel Howard | 0.02 | Open 1st |
| 9 | Flatow,A (Fred) | -0.01 | |
| 10 | Drastik,Penelope | -0.02 | |
| 11 | Huynh,Arthur | -0.10 | |
| 12 | Allison,Graham | -0.10 | u1800 2nd |
| 13 | Tefanis,Frank | -0.12 | |
| 14 | Plaza-Quinteros,Francisco | -0.12 | |
| 15 | Brown,Ted | -0.26 | u1600 =2nd |
| Ineligible players (not enough rated games): | |||
| 16 | Ahmed,Zafar | 0.00 | |
| 17 | Merhi,Alexandre | -0.11 | u1800 3rd |
| 18 | Issa,Mostafa | -0.39 | |
| 19 | Zirdum,Ivan | -0.43 |
The last column is the standard official rating category prize the player has won. It’s not based on the improvement score.
I think this shows how the standard rating category prize distribution fails: in the cases 12, 15, 17 the players performed pretty badly given their current ratings but still won u1800 or u1600 prizes.
Also, Sami Ullah had an impressive performance but got only the equal 2nd prize under 1600.
