The two half life horizon
when it comes to carbon 14 i amprepared to say that it can be on target with dates less than 11,000 years, approx.. anything more than 2 half-lifes i discard, dismiss and doubt.

Could you perhaps provide your justification for this claim? What occurs at two half-lives that renders the technique suddenly invalid and subject to being discarded, dismissed and doubted?
