How is this possible? I can't think of any reason to be honest. Thanks for solving this out
This is possible because for tournaments we use ICM (the Independent Chip Model) to calculate what your luck adjusted winnings are. There are cases where your expectation is positive in chips but negative in dollars according to the model, especially around the bubble.
In this model a single chip has different values in terms of dollars depending on the size of your stack and the number of players around you - it is not worth the same for every single chip.
A simple way to see this in the PT4 ICM Calculator is to create a 9 player 50/30/20 SnG with a buyin of 10 + 1 and starting chips of 1500. Have 3 players left with chip stacks of 6000, 4500 and 3000. You'll see the expectation according to ICM to be $33.14, $30.26 and $26.60 respectively. Now you can clearly see that the chips have different values - 6000 - 4500 = 1500 and 4500 - 3000 = 1500, but 33.14 - 30.26 = 2.88 and 30.26 - 26.60 = 3.66.
The chips are worth more when you have a shorter stack than when you have a larger stack.
Since 1 chip does not always equal the same fraction of a dollar, these graphs do not need to look all that close to one another.
This is an odd concept to wrap your mind around - it took me a while when I was first introduced to it. Please play around with our ICM Calculator and ICM Quiz and hopefully it will help you get more comfortable with it.
Also I'd just like to add that we have been moving away from using the term "EV" - we cannot truly calculate your expected value without having detailed range information for your opponents. We can adjust your winnings based on what we actually saw but since we don't know real pushing ranges, "EV" is not truly an accurate term here.
