Sure, it's neat they can pin things down to a lifetime now. But for most digs, a range of a couple centuries was already fine. This just seems like extra detail for specialists, not a big deal.
Honestly, when patriciab87 says it's "extra detail for specialists, not a big deal," that's way off. Tbh, pinning stuff down to a decade can change how we see whole time periods, not just help experts. It's a big step for everyone, not just a niche thing.
