Sorry for not replying

Andrew is actually right, T=B/sigma is what I need.

Stepwise sound interesting and it shouldn't be to difficult to implement it
using a simple while not statement and run the loop until a certain level of
confidence. However for the time being I am happy with Andrews advice.

Cheers,

Klaus
