"My teacher hasn't added or amended any of the kata"

If so then were in a bit of a pickle then are we not?

Those kata, under those names don't exsist in any style of Goju I am aware of.
Nor can I find them in various Shorin, Uechi, etc groups.

Not saying they don't exist, just that I can't find any reference to them--under those names anyway.

Maybe we can narrow it down this way--

Whom taught your teacher?

And whom taught HIS teacher?

Maybe if we trace it back we might find out more than we know now.

Just a thought.

Something else that might help--

What are the other kata in your system?

Maybe we can figure something out by a process of elimination.
