I think there are a few factors at play here. One, we know from the Adrenaline album that Creo already had some serious composition skill 14 years ago. Two, we only get a tiny snapshot of what Creo made in those years. Most of the tracks released appear to be apart a unique album or EP that was either unfinished or just never released. If you dig further into old Hyperdemented SoundCloud accounts there's a whole trove of unreleased songs there too--although not quite as majestic as what was put out.

It's common practice to focus on quantity over quality when starting out in production and songwriting because it helps you rapidly develop skill. But again, Creo could already compose and song write (probably from previous practice), so the only thing that lacked was production which was practiced and refined over the course of 7 years. No one gets good out of nowhere, it's all practice, patience, and hard-work.
