So not pre-activating is akin to underpitching?
Smaking the pack does not replace making a starter. It just shows that the yeast is viable. You really need to make a starter for most brews except for low gravity beers. Just one pack for most beers is underpitching.
I did a saison with 3711 yesterday afternoon. Pitched at about 6 and was going crazy by the time I got up this morning. I did an appropriate size starter.
You should be ok unless it was a really big beer. The yeast is just reproducing now. 3711 is a beast and will chew through just about anything.
