I’d rather get my information from expert chemists than BRS videos who just parrot what they read without any logical reason besides trying to throw in some buzz words to make you think they are making sense.
Here’s what an actual knowledgeable person says.
I have never once, in decades of advising on reef chemistry, said “don’t chase numbers”.
Chasing desirable values, when done in an appropriate fashion never leads to instability.
It’s how you chase that matters!
And WWC (who BRS collaborated with in that video) literally chases numbers. They specifically chase higher nitrates.
