How can you take up a challenge when he says...
"Note: Lately, for security reasons, session reports are not necessarily presented in real time corresponding directly to the day played."
And we don't know what casino.
Also, "good for the duration of each Vegas trip."
There are too many weasel-out situations. Once you have your proof and he thinks you got him, he could suddenly say, it's too late as he has already ended his trip.
It's a fake bluff challenge set up in a way that he can't legitimately be challenged.
Do we all remember how when KJ claimed he had evidence on MDawg and his Win/Losses and suddenly MD had a huge losing session to then break about even for the year?
