We can go for more precise calculation:
Our first ODI series is against NZ who has 116 points more than our points(0), India and Zim have 102 and 59 points respectively more than our points, that means the second formula applies:
We shall get 90 points for each win, 40 for each tie and 10 for each defeat,
then rating will be =(0+90xnumber of win+40xnumber of ties10xnumber of defeat)/ 25 [to the nearest whole number]
Against India it will be similarly:
Rating=( Rating after NZ tour+90xnumber of win+40xnumber of ties10xnumber of defeat)/ 28 [to the nearest whole number]
Against Zim:
Rating=( Rating after India tour+90xnumber of win+40xnumber of ties10xnumber of defeat)/ 33 [to the nearest whole number]
Note: By the time Zim will play with us, their points will be changed (to the negetive side), which ultimately will change the last scenario.
In the case, when the point difference between BD and Zim becomes less than 40 :
Rating=( Rating after India tour+{Zim point+50}xnumber of win+Zim pointxnumber of ties+{Zim point50}xnumber of defeat)/ 33 [to the nearest whole number]
