Spent 3 hours chasing a rear derailleur skip when my hanger was bent the whole time

Last week a guy brought in a bike that kept ghost shifting under load and I kept messing with cable tension before I finally threw the alignment gauge on it and saw the hanger was off by a mile. My park tool DAG sat in the drawer for 2 years because I trusted my eye instead. How many of you check hanger alignment first before touching anything else?
