Semis situation still very tricky for Pakistan.

Well 300 is a near impossible scenario in T20. 180+ is more like it. say Windies score 200, if NZ win in the last over it WONT boost their NRR. If however they chase it down in fewer overs (say 17) their NRR MIGHT improve depending on what it had been prior to that game

Remember NRR = TOTAL Runs FOR/x no. of OVERS minus Total Runs AGAINST/x no. of OVERS
