Is two what you call a number of certificates from distant instructors?
I'm not sure why you are unfamiliar with 'rank for recognition'. Just like the KKW relies upon the individual instructor in promotions, and recognizes them at a certain rank under their banner, so did the WIF.
I have certificates from my instructor(s) in TKD/HKD (now called KSD) as well as my instructor-only L.E. specialty certificates from the regional training center where I was an adjunct instructor. And one from G.B. when I belonged to that organization.
I am critical of 'some' TKD/HKD promotional practices. And with good reason.
I found it interesting that in Tiwan non of them test and ask for KKW rank beyond 1st Dan just enough to qualify for WTF competion rules after that it is all thier own KwanJang certifications. They do not wish to support KKW financially I would like to know if Ernie Reyes Senior with his own Kwan West Coast Kwan only uses his own certification for students? or has a dual promotion method ?
