You know why. Some of these are trick questions.
Originally you implied that the SAP was an SPA to create ambiguity and confusion. When I called you out on it, a long time ago, you pretended it never happened. The approval process for an SPA is much like and IND, you submit it until there are no more comments over a period of time, and then, you may proceed.
As for any ambiguity on time lines, they indicate at each step that events are advancing. They do not have a requirement to announce and at some point it is reasonable to go quiet. Additionally, it leaves shorts in the dark to some degree, which is likely a good strategy.
Enjoy the ambiguity.
