| January | 19 | |
| February | 18 | |
| March | 15 | |
| April | 20 | (0.10*19)+(0.30*18)+(0.60*15) = 16.3 |
| May | 18 | (0.10*18)+(0.30*15)+(0.60*20) = 18.3 |
| June | 17 | (0.10*15)+(0.30*20)+(0.60*18) = 18.3 |
| July | 19 | (0.10*20)+(0.30*18)+(0.60*17) = 17.6 |
| August | 22 | (0.10*18)+(0.30*17)+(0.60*19) = 18.3 |
| September | 23 | (0.10*17)+(0.30*19)+(0.60*22) = 20.6 |
| October | (0.10*19)+(0.30*22)+(0.60*23) = 22.3 |
