I consider thriving as displaying great colors and solid strong growth. Which given the right flow and nutrients I believe pretty much any acro can thrive with 150 par. There a big difference between too low of par, enough par, and more than necessary. I'd also say poor growth structure is just as much to blame on inadequate flow if not more so than inadequate lighting.
If you haven't yet, check out Dana Riddles video on the study he did in Hawaii. He did a study on corals in a tide pool just a few inches deep getting as much light as physically possible and it revealed that high light corals go into photo inhibition far quicker than you'd think.
Anyway, flow, light are both important, obviously, but I think a coral with higher lighting but lower flow will struggle compared to a coral with lower par but greater flow... Everything else being equal.
Again, I don't want anyone to take this as me trying to convince you to change what works. Just a friendly exchange of ideas.
Oh, and I a agree, the importance of alk, particularly stability, can't be overstated.
