I think it depends on your company rather than saying "most". If you are in a software company (i.e. you sell the software you write), then your value is the unique IP you create from writing code. In that case, hopefully a larger portion of your day is coding.
edit: When I say coding, I don't mean plumbing code, I mean something that is actually a unique invention.
I have delivered successfully projects using Scrum, but we were fortunate that our Scrum Master was well trained and a senior engineer. Our CTO also let us figure things out, and helped us when we were blocked. He was genuinely concerned with the team having a balanced workload, ensured we deliver user value and our software was of high quality. Story points were not used as performance metrics but a tool to help provide stakeholders with some estimation, but only when our velocity became stable. Overall, our process was light-weight, we spent most of our time coding, and we pushed hard to deliver value to the user. If we fell short, we learned from it, no blame, just learned.
As a parent, I'm hoping this will reduce the at-home workloads and shift more work towards school. What's the real life value of having students go to school and then spend all-nighters trying to do homework and all the expected extra-curricular?
