Think of 20 sports books in Las Vegas where you want to bet games, but each book will accept only a portion of your action. They each allow you to bet a different subset of games. They each offer a different juice. Some are even money, some are 100-101 for, some are 100-102 for, some are 100-103 for. When you add them all up, you have a slight but clear advantage.
You spread your money around and bet your array of games. Some win, some lose. Some weeks you lose more games than you win. Some weeks you win more games than you lose.
What kewlJ refers to as "accumulated EV" refers to a measure of how those bets were distributed, win or lose. Some weeks, placing wagers at mostly the 100-101 places, you had a certain small "accumulated EV." Some weeks, placing bets at places where you were 100-108 or more, you had a much larger "accumulated EV."
The games' results determine your weekly cash wins or losses. Tracking the EV, however, tells you to what degree you had the best of it each week. Some weeks you had miniscule advantage, some weeks you had substantial. Results don't enable you to clearly track this. Keeping "EV" records does.
