Bhagwhan THANKS for that, that is EXACTLY the kind of answer I am looking for, now could you kindly tell us the maths used to arrive at those answers, so I can apply it to other examples?

Crash - Grade 3 schoolboys know the maths for working out the odds of a series of outs as in your example. In that respect, with a calculator or Excel I can happily calculate the LIKELIHOOD of any series of outs, which is the maths you provided, but that's not the question I asked. The question I asked is what run of outs should one prepare to expect at some point, given the strike rates, and THEREFORE what is a safe betting level, given the strike rates? That is exactly what Bhaghwan has endeavoured to (and seemingly succeeded to) answer.

No harm though Crash, always do enjoy your electic posts.

But, again, Bhagwan, show us the maths please?
