I told Cos a story today and I will reproduce it here, as some of you are getting distracted by pointless detail.  First of all, understand that even if you had the right game, he couldn't post +20k because then it would be clear to many that to make that much % there was IR risk and not a pre-kick off arb.

OK, back to the story:

A young man goes to a casino every day with 10k.  He nicks 200 each day martingaleing and has a nice life.  One day, ofc he knocks the whole lot in.  It than unfolds that the 10k was his bosses and he was doing the bank run.  So the young man tells the police he was mugged.

If you replaced "mugged" with "slept in" then the penny may drop.

The 10k is actually our 80k, the 200 a day was a bit more than that, enough for a few spins and some GUKPTs.  It all went tits up and there wasn't a "mugged" option - so "slept in" it was.
