How long does an SEO authority cluster take to rank?

Hey everyone — been going down a rabbit hole on this topic and wanted to get some opinions. How long does an SEO authority cluster take to rank?

I came across this article that breaks it down pretty well: https://www.seo249.com/blog/post/seo-authority-cluster-system-the-complete-guide

Their take is basically: Most clusters start showing movement in Google Search Console within 60 to 90 days. First page rankings on the pillar keyword typically land between four and six months after the full cluster is published, assuming the site has at least a modest existing domain profile.

Curious what you all think. How many supporting articles does a cluster need? Has anyone here actually tested this or seen different results?
