Question about tolerance stacking on prints - am I overthinking this?

Found out last week that a .005 tolerance on a part I drafted added up to almost .03 across six parts in assembly. Caught it because the machinist called me out. Now I'm wondering - do you guys chase every single tolerance or just let the shop figure it out on fit up? Seems like two camps on this.

Are you trusting your gut or running the math before it leaves your desk?

Oh man, my tolerance stack once turned a simple bracket into a wonky art piece.
