I'm happy to answer as best I can! but I'm having trouble understanding what you're specifically asking.

If https://news.ycombinator.com/item?id=47327129 and https://news.ycombinator.com/item?id=47328465 don't answer your questions, can you maybe try picking the most important question and making it as specific as you can? Then I can take a crack at that and we can go from there.
