Good post Dhakablues.
Yes, we are not sure yet how to approach the batting PP. If we recall correctly, for a long time, we even didn't know the correct approach for the initial PP's, until Tamim came aboard. Due to lack of aggressive openers, we had to resort to Aftab's slogging at no.3 to make up for the docile approach of the openers that time. In a way, Aftab was sacrificed, and he still can't recover from that. In any case, Tamim made sure we no longer have to worry about RR in initial PP's. Just like then when we didn't know what to do with the initial PP's, now we are dealing with what to do with the batting PP. It will come with time. As an inexperienced side, things will move slower for us than other major nations, who are matured and flexible enough to adjust to new rules on the fly.
We should definitely experiment more than follow the script of waiting till the 45th regardless of situations. For example : If Tamim is still there after initial PP's, which also means, we have a flying start, we should take it right then. If we have wkts in hand, and a nice partnership already built in the middle overs, then I would rather see the two set batsmen take the PP than waiting till the end. In another words, it has to be a in game situation, and since every game is different, the timing of taking the PP's will vary from game to game.
We will figure it out eventually.
