I pitched s-04 onto a stout with an OG of 1.073 (I know interesting yeast choice) and fermented at 65 degrees and it was still done for the most part 4 days after pitching (It still bubbled every couple minutes for the next week or so). Let it sit for a few days before going to secondary, or follow the other crowd's argument and just let it sit in your primary for two more weeks and then bottle.
It's up to you.
It is not certain that everything is uncertain.
