Above calculations are wrong for the case if Bermuda bats first and get all out on 50, If BD makes those run in 5 overs then BD will overtake India NRR.
At present NRR: India = 5 (commulative, 2 matches) BD = -4 (commulative, 2 matches)
If india beats SL by narrow margin say 1 run or in the last ball then their NRR remain same as 5 (commulative, 3 matches).
So BD has to cover a difference of 9 (-4 to 5).
if Bermuda gets out on 50, it means their RR is 1 in that match. so if BD makes that runs in 5 overs it means their RR is 10. So the difference is 9 (10-1). In tat case BD will overtake India

sorry sir! you made the same mistake as the above fellow... it is sum(a,b,c)/sum(d,e,f)... only in case of overs (d,e,f), if a team is all-out in less than 50 overs, their innings is still taken as 50 overs long...

cumulative sum is not done that way dear... x1/y1 x2/y2 is not equal to (x1 x2)/(y1 y2)... the second one is the cumulative run-rate, while the first one is average of the run-rates (which has no mathematical significance, since all matches do not last equal overs, i.e., y1, y2, y3 are different for each team)... time to get back to Class VII algebra, right buddy?

you answer your question urself. NRR indeed is a/b added to c/d. Average is taken every match and add those average and then divide by number of matches played.

cumulative run rate is not average of averages... suppouse u make 300 one day so ave is 6... next day u make 250 all out in 40 overs ave is 6.25... then net runrate is NOT 6.125... it will be 5.50 because in the second match no of overs will be taken as 50...
otherwise all teams would try to make 300 all out in 30 overs, in that case nrr would be 10 which wud be directly averaged... not like that

Dear Arnab, I am not saying that. In each match you have calculate the difference of averages of two teams, then you add those difference and divide by number of matches played then you will get the NRR. I can bet on that.

You calculation is totaly wrong. In this case, I would prefer rediff. You are just referring bangladesh to -4 per match. But what a word rediff gave to this group... Wow I loved it.. Group of death
