Both teams known for their batting collapse and looking at current scenario Pakistan already reached at respectable total. Pitch is still alive so who knows if its low total game, we might see result despite bad weather.
Two days gone and not even one innings completed till now. I would be really surprised, if this match doesn't end up as another boring draw. Weather predictions are also not looking that great. Heavy rains are predicted for the next three days and we can expect the same situation we had during the first two days. I don't expect more than 100-150 overs of play to happen in the remaining three days.
Your calculation is not wrong as weather forecast backing your statement but you are under estimating might of modern day batsmen.. Pun intended
