First of all too finer crush can result in dough balls, it also can cause a stuck sparge, also the final wort could be darker than you wanted.The plus side of a finer crush is that it can improve efficency.
What I prefer is to crack the hull and expose the starch without completely breaking up the husk.

I will toss this out there as a word of caution. Do not assume setting a mill gap to a certain width will correlate with a certain efficiency. The crush is very dependent not only on the gap but the style of rollers and driving speed. For example, I use a MattMill Kompakt love the mill but took a long time to dial in. I tried setting the gap at 1.2mm but had dough balls all day. Dialed it up to 1.4mm and now have a consistent 80% efficiency. I use a gear motor to power so my speed is consistent at 60 rpm for anyone wondering. Just my .02
