Difference Between a Trend and a System

I recently read on one of the forums I follow about a great new system that someone came up with. The gentleman’s system was simply to take the NY Yankees every game on the run line (this means they would have to win the game by two runs).

He based his system on the fact that this year the Yankees on the run line through May 14th were 22W-12L on the run line. That is very impressive.

Unfortunately from May 15th through July 4th the Yankees were only
19W-27L on the run line even though they had a winning record during that time.

If you read one of my earlier posts on run line betting you will see that in time, it is not a money maker. The reason is because there are so many one run games in MLB.

A trend is a short term series of events that typically is spread over 100 games or less. Trends are meaningless and often times they are team specific.

A system on the other hand is typically based on 1000 or more games and can never be based on just one team. It needs to be based on the whole league regardless of which sport you are dealing with. Keep that in mind next time someone has a great discovery that is based on a statistically insignificant number of games or on the results of just one team.

Systems can work, trends cannot.
