ICM calculation

I found this article and I'm having an issue with one of the figures. Can someone tell me where it came from please.

This is the link to the article

And this is the number highlighted in red below.

Raising all-in means we win the pot 60% of the time which gives us 6,500 in chips for an equity of .3649. It also means that we lose the pot 40% of the time for an equity of .2 because we will have gone out in third place and in this case third place receives 20% of the prize pool. When we add up the equity for pushing all-in we get

(.3649 * .6) + (.2 * .4) = (.21894) + (.08) = .29894


Thanks.

Omg I'm so dumb, I saw where it came from 3 seconds after hitting the post button.
