This is the wrong way to look at getting traction on HN. The more you do it, the more likely you are to fail, with the modal case being that none of your posts get any attention at all. I can't tell you how many people we see who think that a clever title and posting at the right time and attracting upvotes in a tricky way will get their content noticed. It pains me to see people spending their energy on something that we know from experience won't work.

What matters is whether an article is interesting. That's what you should spend your effort on. An interesting article doesn't mean you'll get noticed, but an uninteresting article means you won't. Articles that try to make a system out of how they succeeded on HN always miss this point. In reality, what happened is that they hit on something that the community found interesting. (In this case, it was how Nike sold its first shoes.) Then they try to generalize based on the mechanical tricks they used. But those are not what made the article interesting.

What makes this difficult is that it's hard to produce interesting articles repeatedly when your motivation isn't curiosity but marketing your business. With most content marketing articles, you can feel what the author was solving for: "What's a thing that HN would find interesting that we can use to market our startup?" You can even imagine the brainstorming session that led to that topic getting selected. There's a limit to how interesting such content can ever get—if it's not something even the author is intrinsically interested in, why would it excite readers?
