Has anyone noticed improved hash rate by updating cgminer on the Antminer S1?  It looks like the latest firmware from Bitmain is running cgminer 3.12.  I just got mine recently so that's the version it shipped with and it's been running without issue right around 180GH/s each (I didn't overclock... my 750W power supply probably couldn't handle any extra load since I'm running 2 S1's off of it.)

I read your instructions and it seems pretty straight forward to update since I'm very familiar with Linux and ssh.  I'd just like to know what practical benefits I would get from updating.  I'm kind of leaning towards "if it ain't broke don't fix it" unless it would help me out in some way.
