Everything that I've heard and read is that the absolute minimum is Satisfactory for the In-PFA, and Good for the Out. Plus, I don't think that the word "Probationary" equates to anything similar to passing. I'd make sure to hit and exceed Satisfactory to be safe.
Even though my run still sucks, I'm going up there ready to push all day, everyday. That way I won't be surprised if/when that becomes the reality of the situation. As tough as it's going to be during the process, I look forward to the progress that will be made physically while up there.
