Of course what you say makes sense as nothing is written in stone.
At the same time, I have no idea how much action she gave them or how long she played

It's as if if you came into a casino and either won or lost $5000 in a 10 minute period
OR, if that happened over a 10 hour period. The results would be the same however the comps wouldn't be.

IMO her host gave her a bunch of BS. Sometimes hosts use a ploy to try to get you to play or spend more. I have seen it done more than once but who knows.
