So I feel like I get consistently low final gravities but I just dumped trub ( after 12 days of fermentation ), and took a final gravity reading from my conical fermenter and it was the lowest I've ever had=1.005. I have brewed this exact recipe several times and I usually get 1.008 to 1.010. And I did nothing differently. I tested my hydrometer on some arrowhead spring water I had ( did not have any distilled) to make sure it was accurate before taking the reading. First five days I fermented at 65, then up to 68 for 3-4, then at 70 until now. My original gravity was 1.063. Here is the recipe below. Does this make any sense to anyone?

That's a good point. I do always do starters but usually try to get the calculated numbers close to the ideal pitching right. This last batch I did over pitch though. On my IPAs I do always use Chico. Come to think of it, I made a stout recently and used 007 and it finished right where I thought it should so maybe that is the issue.
