You figures are based on everyone striking - that is ill-informed and delusional. It is not going to happen.
29% of total crew said no to the last deal. That in itself suggests that strike action is a minority driven outcome. When I speak to my colleagues (am a CSS) many of them, and many of those who post on here, are more than willing to work.
And quickly doing the maths there are more than 2000 crew who are not union members who will be required to work with minimum rest to ensure flights are crewed - based on your example, you do the maths.
It seems you have your logic for this, and I have mine. Lets leave it at that.
