Shot in the Dark statistics

Is there a general statistic for how many Shot in the Darks in the game right now could be "Not Safe" vs. "Safe"?

Since Genevieve's and Dee's plays so far this season were both "Not Safe", does that mean others have increased odds of "Safe"? Or is it totally random, and there might not even be one "Safe" out there?

I'm assuming this information isn't public, but I wonder how production goes about that and if the players have a sense for it too.
