Hey, sorry man. I'll need more time to get around to you; my current life is just too haphazard to be able to sit down and do this at a set time. Hopefully the consistency of names and roles in the newest entry in the Olympic Games series resolves some of these but in the meantime any headway I do make in my research will have to be played entirely by ear. I hope you understand.
Sugimoto and Goto seems straightforward enough. No harm going ahead with that logic. I'll have a bit more free time in the latter half of February. I'll see if I can pencil in some research time for this series (and you) then.
