Six hours a week sounds great on paper but you're paying for it somewhere else. Those 15 minutes are coming off the end of the day when guys are beat, so now you're burning OT or losing the last push before cleanup. I worked a crew in Tulsa that tried the same thing and by week three the reset turned into 25 minutes of standing around and bitching. The real fix is buying a second set of the fittings you lose most, not turning grown men into janitors.

Waited five months to listen back and realize he was right?

Watched my buddy fight the same battle last month and his butter block was basically a puddle by fold two. He swears the fix was chilling his rolling pin too, not just the dough, so give that a shot.
