I have trouble understanding a calculation in Chips (EV adjusted). I have a hand in a heads up SNG tournament, which gets in for all the chips (1000 in total) on the flop with 77 % equity. Yet the amount in Chips (EV Adjusted) is only 17?

When I calculate, I get 270 Chips (EV adjusted) rather than 17. Since my equity is 77%*1000 chips minus the 500 I have invested, when alle the money goes in. Also, the cEV Diff is wrong by the same amount: it is minus 483 for the hand.

Does anyone know what might be causing this, or whether there is something I am missing?
