FB Plus

I started my account over a month ago when I started the fb adventure program. I finished it, marking all my workouts "complete". Then I decided to join FB plus. I'm wondering, did it add all the workouts I completed in fb adventure to my stats in fb plus?

How does it know to add the videos to my fb plus stats? by my adding them to my calendar, by marking them complete (i'm not seeing that button now, but I saw it in fb adventure), or just by watching them from beginning to end?

Thanks so much for guilding me in my fitness, I truly appreciate it.
