I sometimes think with calves either u got em or u dont. I dont even work mine and there pretty much perfect. Of coursw at one time i did, but now i just maintain. And if u dont beleive me look in my gallery.lol Anyway if they dont respond to a year of intense training on them, I wouldnt expect them to grow much bigger and do high reps when it comes to calves. Nothing under 20 reps.
