University Park sits in a moderate-heat band, not a freeze belt, so the failure pattern here isn't ice cracking cable strands - it's slow heat-cycling wear. A cable that spends summer afternoons expanding against a hot drum and cooling overnight, day after day for going on four decades on the oldest of these doors, develops fray at the same predictable point: where it wraps the drum groove. You'll see the strands starting to separate there before a full snap, if anyone looks.
The other driver is simply the age of the housing stock. A door built in 1987 has had roughly that many years of cable cycling, and factory cable isn't rated to last the life of the door. On a wider single door, that cable is doing more work per cycle than it would on a narrower two-door setup, so on this street pattern it's often the single 16-foot doors showing wear first, not the smaller ones.
