I‘m not sure about’ that. I have only written about 45 articles and only get to write 4–6 per month. Mine are mostly tech and they get curated in to their appropriate slots (90% of them.) I average $150/month and mine are typically 4 minutes. The algorithm know how fast someone has read. If it’s too long, they might just skim it looking for something that catches their eye. That does not count for much when it comes to member read time.
I’m not saying you are wrong, just I don’t think that’s solid advice.
