I agree.

A 30% overlap allows be to basically never have an automatic pano merge fail in LR. Though I rarely shoot panos full handheld, usually still from a tripod with at least a ballhead.

Even better, LR allows you to merge a HDR pano in a single action - which has become an important part of my workflow, because it works so well, and results in a nearly RAW quality DNG that can be edited non-destructively.

With one exception: Multi-row panos with 3 rows, where the top row is mostly sky. Even with lots of overlap, LR usually can't figure this out. But the workflow using tools like Hugin or PTGui is so involved (and requires baking the RAW files first) that I usually just avoid this situation. Besides the fact that it's often not the most interesting composition.
