According to NDS SDPWS Table 4.2A "Nominal Unit Shear Capacities for Wood Frame Diaphragms", 15/32" sheathing w/ 10d@6" edge nailing is stiffer than the same sheathing with tighter nail spacing (i.e., 10d@4"), and is also stiffer than thicker sheathing with the same nailing pattern (i.e., 19/32" sheathing w/ 10d@6"). This seems counterintuitive to me. Can anyone explain why?
