Interesting analogy.. I'll take it a little further in the custom/kit car world, it's not unlike the software world. The last 20% takes 80% of the effort, and you can clearly tell the projects that have had thousands of hours put in with attention to detail versus those that haven't. And, not unlike software you can see as a builder where you came from as your craft matures. Looking at a rolling chassis Lotus Super 7 replica I started building 15 years ago, is not unlike my first SaxBasic (VBA) script I wrote not far around the same timeframe. Fast forward 15 years later and it's like really, what was I thinking ? Contrary to brogrammer theory, this stuff is hard, and takes a lot of years of experience and breadth of knowledge to do well.
