Those mistakes illustrate the quality of the research. Those types of mistakes, indeed some of those very same mistakes, appear in article after article written by creationists. They are supposed to show problems with the radiocarbon method, but they show the shoddy research of creation "scientists" instead.
I am working on researching more of the creationists' claims regarding radiocarbon dating, but I have some other things to do which are more important.
Translation: beyond nitpicking peripheral issues not central to the article, you have been stopped cold. Good luck on your “research”! LOL
