I hope you will forgive me, but I don’t understand what means. Is done with the character Blueprint, or is done using C++? Am I correct to assume that the shoulder midpoint of the chosen actor will be the Hydra Base or does the base refer to something else? Is done by dropping the Hydra Plugin actor into the Character Blueprint? Is the Shoulder to Origin offset added using a Blendspace? Is there a kind soul out there that would be willing to give me a breakdown of this? I am unsure of where in the editor to look first.

is purely referring to the vector math required to translate the raw hydra positions (what you get from Hydra Moved event/etc) to actor space.
A T-pose means you ask the user to spread out their arms forming a T (can be standing or sitting). You will capture the position that the hydras report at point, for example by asking them to push a button when they hold pose, then save the Left and Right hydra positions that you get when they do this.
If you then do (Left Hydra Raw + Right Hydra Raw)/2, you get the shoulder midpoint position of your user in hydra space. You can now use calibration point to translate all your future input into actor space.
is achieved by
RawHydraPosition - BaseToShoulderVector - ShoulderToOriginOffset = HydraInOrigin
All of is simply vector addition and division which you can implement in your blueprint.
You can then use the HydraInOrigin position vector to drive your IK setup.

I plan to make an example of how to set up once I get it set up myself, if you’re willing to wait a couple of days.

Very cool, looking forward to seeing your implementation!
