Default us-05 attenuation!?

I've used both dry and liquid yeasts with great success, although the last time I used us-05 it attenuated above and beyond what was required. My og was 1.054 and I ended at 1.007 (That's like 86%!). It was a split batch, and the other carboy stopped at 1.013 using wyeast london III.
-I mashed at 152
-Fermented at 68 for three weeks, no secondary
-It was an amber, so I used munich, crystal 60 and crystal 120.

Is this normal for the us05? I don't think my attenuation has been that extreme with this yeast before... Should I just plan for super-attenuation next time? Does anyone have a favorite dry yeast they use that doesn't finish this low? May be it was just a fluke...

that is pretty normal. That stuff is very attenuative. If I am making something I want to dry out, I will use it every time.

US-05 is my go-to, power yeast. It sucks up sugar like a 2 year old and gets the gravity down low, really fast.

It will ferment down to high lager temps and produce ultra clean beer.

Yeah it will go bone dry it you let it, I for one wouldn't mash below 154F when using that yeast. I have actually quite using the Chico strain because it overattenuates and strips maltiness from a beer. If you are going for something that is one dimensionally hoppy it would be alright, but I hate it.

I mash at 149*-150*, and ferment S-05 at 60*, +/- 2*.

Doesn't everyone?

High mash temperature does not produce maltiness.

Yeah, US-05 is a great yeast. Though I really wish it would flocculate more.

Four or five days at 35*F makes it drop out pretty darn good.
