| 2000-2001 | 14 | = `14 / (14 + 10)` × 100 = `1400 / 24` = 58.33 ≈ 58 | 10 | = `10/ (14 + 10)` × 100 = `1000 / 24` = 41.66 ≈ 42 |
| 2001-2002 | 15 | = `15 / (15 + 11)` × 100 = `1500 / 26 ` = 57.69 ≈ 58 | 11 | = `11/ (15 + 11)` × 100 = `1100 / 26` = 42.30 ≈ 42 |
| 2002-2003 | 17 | = `17 / (17+13)` × 100 = `1700 / 30` = 56.66 ≈ 57 | 13 | = `13 / (17 + 13)` × 100 = `1300/30` = 43.33 ≈ 43 |
| 2003-2004 | 20 | = `20 / ( 20 + 19)` × 100 = `2000 / 39` = 51.28 ≈ 51 | 19 | = `19/( 20 + 19)` × 100 = `1900/39` = 48.71 ≈ 49 |
