Reach, Match, Safety----High, Low---What Is the Etiology?

“How did this whole Reach, Match, Safety chancing on CC originate? I have noticed that some new CC’ers do not know what a High match vs. Low Match is. Others have asked chancers to translate this into percentage likelihood for acceptance, which is laughable.”

I usually avoid saying “Reach” and “Match” because they are used many different ways. There does seem to be some rough consensus about what “Safety” means.
