I am not blessed with the gift of spatial awareness. I understand how to determine the configuration when a group with priority 4 is on the hashed wedge or when the group with priority 4 is on the bold wedge and priority 3 is on the hashed wedge. However are there any rules I can follow for situations as shown in the image? The numbers show the priority.

To do this, Put the lowest priority group as far away from you as possible.
In the 1 example, if I look at 4 from between 1 and 2 it would be farthest away from me. And i will see that the 3 group is on top, 2 on my left and 1 on my right.
And now if i move from highest priority group to lowest (1-2-3) it would be in clockwise sense. So the configuration is R.
2nd and 3rd example has S and R configuration respectively.
