Ok, now I am not that great with math, but I do know slots.
You still have a huge variance among slots types, it’s impossble to lump them together like that. If the player chooses one of the type slots that have lots of small payouts they will be wagering a lot more. Fortunately the really fun slots most people are playing these days do offer lots of smaller wins to keep the player playing a lot longer. Slots are beginning to be geared towards entertainment value rather than click to win machines. And that makes people wager smaller amounts (or larger ones as they become more seasoned) many, many times over which is great for this system. Every win they have, they play back because of the small size of the win. When people have one large win, they are much more likely to cash out and go buy that new TV or whatever.
I do not have a big winner playing it back so far this month, but the stats seem right on target.
How well you do with this depends on what type of players you send. If they wager a long time you do well. On this system you want to market entertainment value.
