Search around here for threads regarding protein rest for more info.
I'm not so sure this "protein rest" is really a protein rest at all, but I might be missing something and could be totally wrong.

Regardless, I do know that protein rests are basically not needed for well-modified malt, and almost all the malt we work with nowadays is well-modified. So I don't think you really need to let it rest after steeping if indeed you are accomplishing a protein rest by doing so. Doing a protein rest with well-modified malt can actually be detrimental to the body and head retention of the beer.

I've only done one protein rest ever in all-grain brewing, and that was when I was doing a triple decoction using under-modified malt.

EDIT: Removed the bit about FAN - don't think that part was correct.

If I were to get over that threshold for any length of time, squeezing the bag would be bad.
That makes sense, thanks.
