You seem to want to make radiocarbon dating into some kind of second-rate guesswork. That is not accurate.
I have been working with radiocarbon dates for some 25 years, and know a bit about the process. I'll trust the professionals I work with and the study I have done.
Bye.
Yeah, for the guy who thinks that labs are 'measuring dates' rather than extrapolating C14 data, it's probably best that you drop the subject.
