I agree 100% with what Stealth said. I believe the best use of complexity is not extra EV per round but extra EV by increasing longevity. You can do the same with a simpler system but you can't determine the cost of looking like you aren't counting as well as you can with a complicated system. My favorite complicated systems make you look stupid when you are actually being smart. Of course the developers of such systems don't share them publicly because they use them to make money. Once they become more obsolete they may share them.
