...Thickness at point of nailing at panel edges determines allowable shear wall values. A copy of ESR-2586 is attached.
I've been conservative by assuming the 1/4" deep grooves effectively make the panel only 3/8" thick (for 5/8" T1-11 siding). Good to know that you can use the total thickness of the panel for shear.
