Often when playing slots if there is some mechanical malfunction the attendant has to reboot the machine and during the process one of the screens that comes up lists coin in/coin out/jackpots paid etc allowing you to see what the real return on that particular machine has been. Has anyone ever seen this on a VP machine and how has the actual return compared to the theoretical return? I suspect (without any evidence to support me ) that the real return would be a few % points below the theoretical as most people don't play perfect strategy. So if playing a 97% return game the real return is likely closer to 94% which isn't a lot higher than high denomination slots. It raises the question why do casinos discriminate so horrendously against VP in terms of multipliers/points earning etc? I know that various Gaming Commissions publish the actual returns on various denomination slots. Do they give a breakdown for VP machines? I'd be interested in some data points if anyone has seen one of those machine payback screens.
