If you are overpitching yeast, especially the chico strain, it can really dry and strip everything out very quickly.  Which could be where your consistently low FGs are coming from.  What is ballpark for your normal pitching rates?

 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.
I am a great believer in luck, and I find the harder I work, the more I have of it.

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?

Batch Size: 6.33 gal   Style: American IPA (14B)
Boil Size: 8.50 gal   Style Guide: BJCP 2008
Color: 6.0 SRM
Bitterness: 62.0 IBUs   Boil Time: 60 min
Est OG: 1.062 (15.2° P)
Est FG: 1.013 SG
ABV: 6.4%

Mash 60 min @ 150

Ingredients
Amount   Name   Type   #
10.82 g   Gypsum (Calcium Sulfate) (Mash 60 min)
13 lbs 5.40 oz   Pale Malt (2 Row) US (2.0 SRM)
9.19 oz   Cara-Pils/Dextrine (2.0 SRM)
9.19 oz   Caramel/Crystal Malt - 40L (40.0 SRM)&
0.54 oz   Magnum [14.0%] - Boil 60 min
0.80 oz   El Dorado [15.0%] - Boil 15 min
0.45 oz   Centennial [10.0%] - Boil 15 min
0.30 oz   Columbus/Tomahawk/Zeus (CTZ) [15.5%] - Boil 15 min
1.08   Whirlfloc Tablet (Boil 15 min)
1.00 tsp   Yeast Nutrient (Boil 15 min)
1.00   Chiller/whirlpool (Boil 10 min)
0.50 oz   Columbus/Tomahawk/Zeus (CTZ) [15.5%] - Boil 7 min
0.30 oz   El Dorado [15.0%] - Boil 7 min
0.20 oz   Centennial [10.0%] - Boil 7 min
Starter   California Ale (White Labs #WLP001)

At flameout, cool quickly to 175 and then whirlpool hop for 30 minutes: 0.8 oz Columbus 2.05 oz Centennial 2.75 oz El Dorado

are your hyper attenuated brews coming out cloudier than normal? Wild yeast is often a very poor floccer and can cloud up a beer.

 No, they actually drop out crystal clear after about a week in the keg.

I think this may be the issue at hand, especially if you aren't seeing any adverse flavors or cloudiness.  I way overpitched the chico strain in a cream ale and it finished at 1.005

Update:
This beer has been in the keg for 2weeks and I am very happy with it.  Doesn't taste too thin to me.  Thanks for all the input.  Next time I will mash a couple degrees higher and see what happens.
