Anecdotal, but I've noticed while this is true it also adds the danger of knowing when to stop.

Early on I would take forever trying to get something exactly to whats in my head. Which meant I would spend too much time in one sitting then if I had previously built it by hand.

Now I try to time box with the mindset "good enough".
