My main issue at a glance is it's too linear "Day 7 Add another round of ingredients. Day 8 You are done".
it doesn't work that predictably. You have to describe the outcome you're waiting for, it might happen on an earlier day or later. For SW engineers, it's a "while (!ready())" loop, not a "for (day in 1..8)" loop.
Maybe it worked that way once for the OP. But it will vary. For SW engineers, this is a "works on my machine" type issue.
I feel like once flour was invented sourdough was inevitable. Adding water to ground up grain is an obvious move as it binds it and makes it easier to work with. At some point a flour/water mix is going to be left standing and start bubbling, and when cooked it's going to get magically bigger. Boom, bread.
I enjoyed the post, always glad to see anything bread related. Baking bread has been a huge positive thing in my life, I'll never stop now (I was even without an oven for a year and learned to bake bread in a cast iron pot on a gas burner/hob). It's a rich sensory experience with all the smells and textures, and working dough is very grounding and 'real'. Every loaf is different and it's great fun waiting to see what's going to come out of the oven. I'd massively recommend getting into bread!
For starter feeding, though, I'm with the GP post: measuring all the time is a PIA, and totally unnecessary. The margin of error is massive, after a few measures you'll know the consistency to aim for, and if you're too stiff/wet it's dead simple to compensate when baking.
Feeding by texture lets you get to know your starter better, follow its rhythms, and makes daily feedings a very easy habit to maintain. We've been pulling this off for 5,000 years without a digital scale :)
I personally use the big measurements (flour, water, etc) as a rough guide so that I'm in the right ballpark on consistency and don't need to add too much one way or the other to get it right, and usually ignore the smaller measurements entirely (salt, baking soda, cinnamon, vanilla ...) and pour what looks like an appropriate amount in my hand before dumping it in the mix. Fewer dishes to wash that way :-)
You can get lack of consistency with an accurate scale, just always experiment, e.g. vary a weight. That way you know what you did also get _repeatability_ if you like the result.

Sourdough bread famously has only 4 ingredients: flour, water, salt, yeast (starter). Though that's not the whole story, there is also seeds, and more than one kind of flour sometimes.

Measuring by weight is exactly the same, the mixing bowl is on the scale. pour in until the right weight is reached.
If you use the same flour every time, and are aiming for the same consistency, then you will want roughly the same amount by weight of it each time. I get that you don't need to be that precise for the starter, but I don't find the weighing process at all hard.
What was the results like? This post piqued my interest but I don't have an oven in my home. Only gas stove top and a tiny gas grill.
