That's right free play is in the future. But kewlj is arguing that his $8800 loss is part of his overall EV. Go back and read what he wrote.

Hence the question: how much is his loss worth? He argues his $8800 loss gave him "my best day of the year" for EV.

THIS IS WHAT IT'S ALL ABOUT. NOT THE VALUE OF FUTURE PLAY BUT HOW KEWLJ VALUES AN $8800 LOSS.
