Question About Offset

[JingukKim]

Hi, thanks for the good research.

I have a question about offset.
Predicted offset value is in [-0.5, 0.5].
But when sampled query_xyzs have minimum distance 10 beween them, predicted center couldn't cover all possible center area.

For example, there's two query xzy for simplicity.
query_xyz0------target center----query_xyz1
Distance between query_xyz0 and target center is 5
Distance between query_xzy1 and target center is 4
Since offset value only can get value [-0.5, 0.5], predicted center never can get the same value with any target center.(Best difference is 3.5 -> Isn't it big?)

Please help me. Thank you.
