@dave1311: I have no idea why you need to insult me. I certainly do not feel privileged and yes, I can deal with losses if they make sense and are plausible.
Your post however is arrogant ("I often beat teams 29-30% stronger than me") and illogical, because one the one hand you pride yourself by claiming to beat better teams regularly, yet at the same time praising the unpredictability of the game.

Please try to use better logic next time and don't be so full of yourself. Your record is nothing extraordinary.
As for me, there are several threads here now dealing with these issues. I still think it sucks that managers who put in a lot of time and do everything they can basically get screwed by the AI. Every now and then is ok, but this is happening way too frequently now.
