I recently made a split batch of Jamil's Ordinary Bitter at 3.7%.
One half I did to style; the other I dry-hopped with 1.5 ounces each of Columbus and Simcoe.
I was somewhat surprised to get a good deal of bitterness from the dry hopping. The "ordinary" side was spot-on for bitterness...
Sounds fine to me. Stores often have a bigger crush to avoid complaints about stuck sparges. My efficiency went from 70 to 80 percent when i got my own mill.
This is mostly wrong. As the quote from Palmer explains, a protein rest, particularly a long one, can be detrimental to head retention. It also has nothing to do with yeast nutrients.
It may, however, improve clarity.
What do you possibly have to do with John Palmer's book? How is it that you're taking email addresses and sending people to his online book? They can go there free. Did you actually have something to do with writing it?
If not, that's pretty sleazy.
