Problems re-sizing iiko

[MadeAtMidnight]

There is a CAT rig resizer (it's under "Animation -- Animation-CAT --- Rig Resizer"), but I am still not quite getting it to work the way I would like. I haven't watched all the videos that the Autodesk folks have put up, but I'll try looking through more tomorrow to see if I can find how to do this.

My team used to use a long and painful process of resizing the iiko and then copying and pasting every keyframe with that size, but we figured out recently that not every keyframe needs pasting, and I really have no way to explain this phenomenon.
I'm not sure if that helps anyone, but that's how we got past it.
