Yeah, I have lights on full power from pretty early on in veg. I don't have a device, so I probably can't optimize the timing as well as you. That's pretty cool.
I've heard of reducing light intensity during last two weeks of flower to increase oil production and preserve terpenes. Makes sense that it emulates the natural change of seasons, from bright summer to the lower light intensity of autumn. But I have no experience with this, nor do I know anyone who's tried it. But I do like extended darkness before harvest, like 36-72 hours of darkness.
