I am trying to understand which of the different TTBs that are displayed in the start view (come-up and pass the start-line, go about and come up and pass the start-line
or fall away - gybe - come up and  and pass the start-line) that is chosen for the TTB and the TTB number box value, and in which situation.

I can see that Expedition chooses one of the three options in different situations, but can not make out on which grounds or parameters which is chosen.

My case is that I want to stay parallell to the line about 5 length below and go about and then start. In this situation Expedition often displays the TTB as the option go about and come up and then start, but not always..
