Well, it depends on what you mean by "justify". We were quite happy to win what we did, and we had an absolute blast doing it. It was a significant amount of money for us at the time, but insignificant to us now. It was well-justified from our perspective. We did everything on $5 or $10 tables, and there were no NMS restrictions anywhere we played (Las Vegas Strip).
I've also never seen NMS restrictions on the $25 tables on the Strip, either, but maybe that would change if someone started betting yellow. We never tried it.
