I'm sorry Don Shelly, if my language make you confuse... my mother language isn't English.

Recently, I have 50 data's weight of necklace, and I would to make standard weight from that data's, could I use Method Definition Limits? And what is connection between MDL and Process Capability Index?

I am sorry, but the calculation that I gave to you won't apply in this situation.
