Burdick's article was flawed, and while it does have some good information in there, I would not use it as be all end all soruce of Korean martial art history.
I don't recall it being cited as the be-all-to-end-all source. It is a source though as is Tedeshi and those that others have mentioned. It needs to be realized that an exact and precise time line of events is quite difficult since histories have been changed or the attempt has been made. It boils down to a senior changing facts around to fiction and then teaching it to those who in turn pass on the changes. Could have been nationalistic pride, could have been ego, could have be x,y and z. Those in the lineage then report fiction as fact and stick to it regardless of what anyone else brings to the table.
