I am not Mr. Salty but I know that he is one of the lucky ones. He doesn't have to do water changes anymore.
As for myself, I do them biweekly. my tanks are small so I need only do a 5gal change. I use a yosimite water bottle, mix the salt and add a heater the next morning. I never worry too much about getting the temp exact, as long as the levels are right and the water isn't freezing. My tanks have been great. SO FAR!!
