That kinda makes sense. I still say grinding finer works though.
I feel we're being ignored. Here, let me be more clear:
There's no need to dick around with mill gap settings. If you don't crush the wheat properly, your efficiency will suffer. If you don't crush the wheat properly, you aren't crushing anything hard enough. Set the mill gap tighter, and crush everything tighter. That includes barley malt, wheat malt, rye malt, oat malt, corn malt (where can I buy some of that!?), you name it. Set the gap tighter, crush everything harder, and be done with it.
