Hi john
Many thanks for the quick reply, and clarification. I now understand how this calculation can be done.
Please note i have viewed all your lectures in relation the the f5 paper, actually, i revisited the lecture in relation to the doubling rule this morning before i wrote to you. But there is nothing in respect to the reverse calculation as in this example.
However, please accept my apologies if i have missed anything in the lecture which should have avoided me asking the question.
Lectures are really good and very easy to follow.
Many thanks emerson
