There’s something about Kansas City and Cleveland going up against each other. I observed two instances where they faced each other(baseball and Am. Football) and the code for the game was the same, as was the outcome! The code for both instances was (U) (U) w(x) where x can be F(favorite) or U(underdog). When a weak aspect (w(x)) is combined with a strong one in a chain, x doesn’t affect the result whether it’s a U or F. In simple terms, U U w(F) = U U w(U).
Over a year ago on July 29th 2020, the Cleveland Indians were favored at home vs KC Royals and it was an ‘upset’ as it went into extra innings where the underdogs eventually won. That game going into extra innings was enough to call it an ‘upset’ regardless of the outcome afterwards. In the home opener for the NFL season today(9/12/2021), the Kansas City Chiefs were favored vs the Cleveland Browns and eventually won by 6 points after trailing most of the game. This counted as an ‘upset’ for my method because the underdog lost within one ‘maximum score of an American Football offensive possession'(td + extra = 8).
If this was another sport like soccer/hockey it would have been a draw(or underdog win). Since ‘draws’ are very rare in Am Football, the majority of ‘upsets’ for this sport have the underdogs losing within 6 points(one possession). For NBA in which a tie is very rare as well, it is within 4 points(one possession). These observations are based on my data of course.
The code U U w(x) is an upset most of the time unless a certain condition that I cannot disclose currently is met.
