No worries, it’s a pretty big forum and some of these things have been requested years ago so they are not always easy to find. 
I’m not familiar enough with what is good on Windows to give you advice on that. Generally speaking however, spreadsheets by definition are good at visualising sequences of numeric data, and at a basic level of usage require almost no special knowledge nor complicated workflows. Just type in your number at the end of the day. Done. If you want to get fancy, there are I am sure good spreadsheet templates out there specifically designed for writers to track their word count productivity.
I’m not sure what that means, could you clarify what you are referring to as a chapter, and how that would be distinguished from other items in the binder? The main problem is that Scrivener doesn’t have any inherent structure. To provide an example that is still within the realm of a “book”, here is a screenshot of one of the chapters in the user manual project:
This is a partial Outliner view of Part III (we can see about 70 of the 250 documents that comprise this part of the manual), with the “Writing and Editing” chapter highlighted in dark blue. The selected item near the top is the container called “Writing and Editing”, but the actual chapter, the part that is going to be edited on a regular basis, is distributed amongst its sixty-six child items. So, if any one small part of that group of items changes, the whole can be considered changed, but the problem isn’t really with that concept, but rather: what is “the whole” here? That’s not even something I could easily predict within this one project. I’ve shown a rather large chapter here, but I also have a few chapters in the user manual that consist of one single text file.
And like I said above, that’s still just sticking within the realm of objects that are broken up by divisions we call chapters. Scrivener is used for all kinds of writing, many of which have no such entities within them.
So those are a few of the challenges with the idea, maybe you have something in mind that could work around it though. Let me know! Something like this would have to accommodate essays, graphic novels, legal briefs, technical manuals, whole seasons of television shows, etc. I.e., the solution needs to be flexible enough to be useful to a wide variety of structures, some very rigid and topographic like the user manual, others rather chaotic and organic.
Perhaps it is a great writing platform because we haven’t spent time creating a spreadsheet in it. 
In all seriousness though, you do say this other program isn’t on par with Scrivener otherwise. A lack of focus can do that to a program. I don’t know if that is the situation here, I’m just making a point.
Nobody has made that argument, so I’m not sure what this rebuttal is aimed at, nor the corollaries that stem from it. We’ve always stated (in fact it is even in the product marketing on the main web page) that no writing program will be perfect for everyone. We actively encourage people to seek alternatives if the demo doesn’t work out for them, and have a whole links page as a top-level navigation tab, dedicated to rounding up as many different approaches to writing as we can.
But entertain that is the goal for a moment: even so, the argument is that we don’t feel it is necessary that writing software needs to have graphing built into it: hence, this premise has nothing to do with making writing software in the first place, no more than a virtual reality 3d interface would have any business in Scrivener.
I understand you disagree with this, and that is fine, we all have different approaches to doing things, but understand that from the stated views of the designer, detailed tracking of your writing is the important thing to be doing here. That is something nothing else can do well since it requires knowledge of the internal system. Tracking what you type and what you delete as you work is intrinsic to the software letting you do that.
Making a pie chart or whatever out of static data that requires no special knowledge to store, isn’t.
You mentioned programming a system of your own to track things in Scrivener, is that something you’d be willing to share?
