I think as with most things there's definitely going to be differing opinions on this but no one is right or wrong. The research shows that in the wild corals can withstand large swings in temperature. That is what they've adapted to. If you keep your tank within 2 degrees and your corals seem fine then that's what they've adapted to. The danger is that if one day a summer storm comes and the power goes out your tank goes higher than what they've adapted to and could stress or kill the coral. On the other hand if you purposely allow swings (within reason) the corals would adapt to that and could fair better in an outage.
I think about it like this. The ph of the ocean, specifically the coral reefs, has not had much fluctuation in the past. But now human activity is changing that and its slowly wiping out corals reefs. The wild corals are not adapted for ph swings. Im not sure but some successful tanks probably have greater ph swings than the ocean. So its all about what your corals are accustomed to and if you think its worth risking stressing them to toughen them up. My blue hippo tang is my temp indicator actually lol. When my temp swings too much she gets ich. As soon as I get the swing down to a few degrees she gets better.
