Shimano Hollowtech II Bottom Brackets Make No Sense | An In-Depth Rant

I couldn't find a difference between any of the Hollowtech II threaded bottom brackets on Shimano's websites.  So, I ordered 3 different ones to find out the differences and now I'm just more confused.  You can find my research breakdown in the Google Doc linked below.  If you know anything more about these bottom brackets, please leave them in the comments!
