Well, assuming he was never going to use either account again, and factoring in vig % on Lock right now, he had a coinflip in equity going into this to break even. Anything higher than that = chip dump ftw. We obviously need to discount some of our equity for the fact that not every 2p2 trade would likewise pan out.
I'm sure many have done this and it's a big reason why Lock is supposedly on the negative side of the reconciliation reports w/ payments to other skins on the network.
