WWC is a vendor. What they do and what a hobbyist does is totally different. They are not great hobbyists, IMO, but they know how to sell corals and promote themselves. People might get something from studying them, but nobody should be using them as a guide to run a tank in their home. A high quality hobbyist is a better paradigm to follow.
IMO, the 2x mp10s in that BRS experiment, is competent. I have told people for a decade that the whole "as much flow as you can get" is more of dick measuring contest that won't matter much. If you don't have competent flow, then it really can matter, but few people screw this up.
We have seen people remove sand to get as much flow as possible and then struggle with phosphate buffering, nitrate removal, etc. Too much flow can cause fish to get skinny and die, corals go grow in stubby and weird patterns or even can melt tissue off of skeletons.
You have change up as your acropora move from frags to colonies. What is competent when you have 1" frags is different from when you have to get flow around 6-12 inch massive colonies. Competency is a moving target.
For me, I like to have flow right up to the max where my sand stays put. This will be less when the tank is wide open without colonies and I have to ramp up when the acropora get larger. When the sand blows around, I turn it down, but a few times a year, I ramp up to see if I can use more.
