With optimal fixed bets:

At NO you have a 84% chance of at least doubling bank?

At 4NO you have a 97.7% chance of at least doubling bank?

What is the % at 9NO?

Before playing up to 4NO or perhaps 9NO would it be correct to say we are in the SD wind and we have to play these number of hands to have a sense of guaranteed income?

thank you very much for your time
