Appreciate the time you are taking. Let me see if I can find an analogy...
Let's say my site was a real estate site (which it isn't). Each page might have a record for every residential address and for each record you can look up ownership info, market value, maybe some links to those addresses on other useful site, etc. So, you could search your childhood address "123 Main St Anytown, USA" and get a similar mix of search results to what my site does. Each town has a page with a list of street name, each street page has a list of addresses.
My traffic drops were more gradual than what I would expect from G updates. My best guess is that part of the pool of searchers became somewhat satiated. That is, some of them search for the same keywords routinely and see what new (to them) sites show up. Or more likely, G dropped me a little in the results over time. Or both.
