Actually there's no such thing as "the grip point for everyone"
What matters is how comfortable it is for you. With the Aeon v4 it's fun because the balance point varies pretty significantly depending on whether the blade is heavy or mid-grade or the length is 32" or 36".
I swapped all variety of blades around in the Aeon and every setup needed a different grip point to get a desirable result. And that's showing how great the Aeon/Dominix hilt is: there's always a choke point to consider

For me the ideal is when the weight of the saber spins itself with the least musclepower added. It does not matter for me how far my hand is from the balance point but what matters is that the whole motion is speedy but light and I have the most power reserve to alter the orbit or the whole move.
So if you are weirdo, I am one too
