I will assume slightly above 60 percent if everything goes well. There really aren't many games I am worried about losing. I would think the real concerning games would be Boston, Minnesota, Washington and Pittsburgh.
Of those, Pittsburgh and Boston are the hardest.
3 games against Buffalo should all be wins.
The Preds, Isles and Habs are all a crapshoot.
Long story short, as good as 7-3-1 and as bad as 4-4-4.
