I do not know the OP's level of experience so I was trying to look at if from a lesser level of experience. ATA has fewer forms as I remember so that would also shorten the acclimation for a person of rank.
He says explicitly that he has a 1st Dan. Of course, he says it's from the WTF (which never issued rank) so who really knows...
I suspect from his OP that he's got a KKW 1st Dan, and hasn't trained in quite some time.
