I) Maybe, only way to know is to check in 3-4 days.
II) Could be but it does not have to be. Only way to know is to taste.
III) You could add a little bit of CaSO4, it will "sharpen" up the beer and tone down the maltiness.
The problem with these kinds of numbers is that there is no way on a homebrew level to know when you are 10% over.
All the calculators out there are just semi guessing. Don't think that you have 259B cells when a yeast calculator spits that out. Maybe you have 208B, maybe 303B.
But...
13.53%.
Seriously, no one can answer that. The calculator is are just estimats that probably are off 10-20% most of the time.
Perhaps you like the beer better when its a 100% overpitch.
This was posted in the extract forums so the boil times are not really important.
Personally I would do a 15-30 min boil and do hop additions at (30)-15-5-0.
My experience is the same. Compared to Nottingham (for exampel) it is slow and takes alot longer to clear. Besides that I don't really like US-05 much and stopped using it a while back.
However, it is pretty robust and given time it will finish the job.
There are alot of diffrent ways to do it and there is not *one way to rule them all*.
What you plan to do looks to me like a good way to do it. My guess would be that
*most people nowdays would skip the secondary in this situation and just dry hop in primary.
*some brewers would the gelatin...
Will it work? Well, you Will get beer. There are alot of reports of US-05 throwing some peachy flavors at low temperature. Fermentis also raised the recommended temp for that yeast a while back.
Perhaps use another yeast instead, like Nottingham?
