Chain slack with stretched swing arm

I've tried doing some searching but having found an answer. I have a 2015 zx14r with a 12in stretched swing arm and was wondering if I still follow the regular procedure of moving the chain up and down and measure the distance between the up and down movement off the swing arm on a rear stand or if I gotta do anything special since it's stretched? Also do I still adjust it to the 1.0~1.2in?
