Are we nearly there yet?

So you're involved in trying to bowl a side out like India were yesterday and you want to know how you're getting on. Obviously the fifth wicket is only mathematically halfway since the tail should be easier to get out than the specialist batsman.

So where is the halfway point of the innings ?

How would you calculate it?

How about taking the total of the highest partnerships for each wicket to create a mega-total and then finding how many wickets were down when the score reached the halfway point in that mega total? Seems interesting so I've done it. You could even take into account how far through that partnership the half total was reached.
All clear?
So the answers are that the mid point of the innings in terms of runs is after 3.675 wickets for Test Cricket and 4.1 wickets for First Class Cricket.

And the mega totals? How would you like to field through 4,772 runs?
