At this point, we really need to stop making up this intuitive vs algorithmic distinction. It’s misleading.
When you’re a complete beginner, you don’t have any experience. As such, the speed optimal solutions probably won’t make sense and will just feel like memorizing a sequence of moves to do something.
At a 15 second avg, you should have a decent intuition for how pieces can be put together. So yes you should look at the “algs” and just do them 1 move at a time to see how they are putting pieces together or setting up into simple insertions. Most of them should be pretty simple to understand that way and will feel intuitive, like someone is just showing you a better way to do something, rather than learning something like a ZBLL, which won’t really feel as intuitive if you haven’t learned enough algs to notice patterns in them.
