So I am contemplating to reduce/leave the forum for a few months. I have also other projects. Thoughts?
I am certain that a man of your means has better things to do with his time than generate Excel trends through historical data and pretend it reveals secrets about the future.
Especially as I reveal a secret to you: just yesterday I hired an excel-wiz to crunch the numbers, and he can even post the charts here! The ominous lack of visualization is just my inability to transmit the graphics

If you've hired a professional statistician on your dime for the community's benefit, we are obviously grateful.
You don't know any folks that know how to do system dynamics modeling, do you? I'd take that kind of analysis very seriously indeed.
