wo ply gypsum shear value

two ply gypsum shear value
does anyone have any values for 2 ply 5/8" gypsum sheathing on each side of a metal stud. the ibc has values for 2 ply gyp sheathing for wood studs, but not for metal studs.

table 2211.1(2) of the ibc 2000????
table 2211.1(2) gives values for one layer of gyp on each side of a metal stud. i am wanting the value for 2 pieces on each side.
i've never heard of any research or data allowing such a thing.  only some tables for plywood over gyp-bd for seismic retrofit.  certainly nothing in the ibc.
i would not rely on gyp board to provide lateral stability! why not use plywood!!
it sounds to me that you are splitting hairs or trying to make lemonade from a lemon.
