What I mean by me researching is skimming through the internet a lot. My corals adjusted to the time change fine.
From what I am totally guessing and tried to make sense of it all on my own is as to why the peak hours in a natural state would be a matter of protecting itself from a more intense sunlight of the afternoon and having fed itself enough from the morning hours making the zooxanthellae in less need of food, because corals/zooxanthellae love photosynthesis for feeding, but not to much light as to where they can expell zooxanthellae causing bleaching. Seen a show called The Great Barrier Reef. When they shine a UV light on a coral they mention that in theory the bioluminescence of the coral that is given off from the coral is from there sunscreen. So that means they do have a protection mode not just a 100% feed me mode.
I like to think it more like a possible degree of breakfast, enjoy the day without "protecting" itself causing less stress with a base light, and then dinner. We always talk about feeding and how much stress can be on a coral and they do show it with signs of being open and happy or retracted and stressed.
So try it. Give the corals breakfast to give the coral enough energy for the day for a few hours of a higher intensity. Bring it down so they can relax for the day with a base light for photosynthesis not so intense so they do not feel like it is feed feed feed shove down their throat all day long and now they feel to a point of "okay I am full now and I can't put up an umbrella to protect myself from this light." Then in the evening they want/are looking for more food to last throughout the night when there is no light to be had. Think of it like this. You eat, then snack, and then eat. So a 80% breakfast to fill you up. Snack 20-30% throughout the day so their levels don't drop. So none of the zooxanthellae is searching for it, because it is available just not so intense. Then 80% dinner to fill you up and rest comfortably. Maybe during that rest period of a base light not throwing them into a protection mode of sunscreening. Gives them time to now refocus on what you are looking for and that is growth mode.
You see your corals best. If what works for you works. Don't change it up. Every tank is different. I like that I get a 2-3 extra polyps a month and when I had it on schedule like this it was 6 every 2 weeks with some zoanthids. Plus during the day I now see my coral puffy, Illuminating from the ati blue plus longer, and I do not have to replace 2 out of the 4 T5 bulbs until June of 2019 due to the amount of use to them. Where if ran them for 8 hours to have a full day peak time. I would be replacing the coral+, 2xblue plus, and true actinic all at once in October of this year. All and all this is how I personally will continue to run.
