"Normal" joint rotation limits?
 

Does anyone have "normal" joint rotation limits that they give to a human arm using IK? I have set some that I think should work but I get strange results such as the arm not moving to locations it should, plus the IK handle seems to "fight" with the Pole Vector constraint. I would position the IK, then as soon as I move the Pole Vector constraint the arm jumps to the new location as opposed to simply easily moving to the new location.

My results with having limits off works nicely but if I can set up proper constraints I would like to. Thanks in advance.
