Flex Shorthand

I understand flex-grow:: it allows a flex item to grow based on a ratio relative to the other flex items on the same row/column.

I understand flex-shrink:: it allows a flex item to shrink based on a ratio relative to the other flex items on the same row/column.

I understand flex-basis: it overrules the main-size value and sets it's width (or height, depending on orientation).

HOWEVER, I don't understand auto and 0 and the like. If you look at this example, I expected that all three boxes would be the same size, since they all are "allowed" to grow. And it's not because box 1 is set to be so large that the others have shrunk, because it's rendered width is much more than the flex-basis of 100px...

This makes no sense to me! O.O

Found out that this is called "relative flex" and the extra space is evenly distributed to the boxes, so box 1 would be 100px+ 1/3 of the extra space, and the others would receive the other 2/3, evenly. This is different that "absolute flex" where the total items' space is calculated evenly, instead of just the extra space. Here's a picture that I figured would explain it but I couldn't wrap my mind around it.

I have spent hours on that page and other websites trying to figure it out. The CSS Tricks page is good for understanding the individual properties but I am not getting how the influence each other. This picture seemed to help, but then as I tried fiddling with the code, I realized I am definitely missing something in regards to how they relate to one another.
