Laugh at me, poke me, whatever you choose, but I have a question that may be construed as dumb. But since I've never claimed to be smart, perhaps I can get away with it. 
I have never hit a royal flush in 2 years of playing VP (.25 JoB). I play once or twice a week, and have become pretty good, and fast. I've practiced with WinPoker for about 5 years.
According to the stats on WinPoker, a royal on a 9/6 JoB occurs every 40390.55 hands. I realize this is with perfect play, and may occur more often or even more infrequently. By my calculations, I have played approximately 128,000 hands in the last two years. This a very conservative figure.
Here's where the dumb question comes in: If and when the royal does hit around the 40,000 hands dealt, does it occur on a specific machine, a specific bank of machines, or hands accumulated by a player over time? I'm guessing the player, but just not sure so I thought I'd ask.
Thanks,
Kurt
