So I'm an idiot. I guess I was so happy that I had enought volume at the end of the boil that I forgot to collect some wort for an OG reading. However, we noticed it as soon as we put the carboy in the fermentation chamber. We immediately took it out and grabbed a sample for an OG reading. I was going for 1.086, but got 1.071. We already aerated and pitched the yeast. I would estimate about 8-10 minutes passed between the pitching of the yeast and the OG reading. Is this OG reading valid, or did the yeast start going that quickly? FYI, I pitched two packs of US-05.
