Interp Two Bone IK?

I’m creating a VR game and I have my Two Bone IK setup for my hands. It works pretty well except it can be a bit laggy between movements. I was trying to figure out if I could interpolate between them.

I see that the Two Bone IK has “Interp Result” but I can’t figure out how to use it nor is there documentation on that section. I tried setting the speed to low and high numbers but nothing changed.

Anybody know how I can do this in the AnimBP?
