Hopefully it’s more accurate.
RC dating has a range of error, which some (falsely) claim make it unreliable. There are also results which get thrown out because they don’t conform to preconceived notions, e.g. the contents of Ramses II’s canopic jars, his internal organs IOW, which dated over 700 years younger than the conventional pseudochronology sez they are (Velikovsky reconstructed the actual date, in 1945, before RC dating was figured out), or e.g. the wood from the Ulu Burun wreck, which was originally trumpeted as nailing the exact date of the shipwreck, until it was realized that it actually did the exact opposite.
