Your opinions, please, on the proper nailing schedule of sheet rock. My mudder insists I use too many screws (3-4 per stud on sidewall and about the same for lids). He explains I should just nail the perimeter - one per stud, then about 4 more screws in the field, using a 4X8 sheet. The above with the benefit of glue. He can't say enough about using glue. Maybe I'm wrong but this seems a little shy on fasteners. I do trust my taper and I believe he's not just trying to save work for himself, although fewer nails would certainly do just that.
