Atkins Video Slot Total ROI vs Average ROI?

I've been looking over the design pdf for the Atkins Diet Video slot atand it occurred to me that there are at least two ways to calculate ROI: either as a total ROI (total out / total in) or an average ROI (total average of each spin's ROI). The results of these two seem like they would be different given a fixed time frame. So my question is this, per that .pdf, which "return" is being shown? Is the average ROI or the true ROI going to be more accurate given a fixed time frame? Or do these two ways of calculating ROI simply mean two different things, and if so, what is the difference?

Thanks!

Not sure I follow the question, but the return on a slot machine is total out/total in. This is the return that you expect to see in the long run. Due to volatility, almost anything is possible over a short period.

Let me reiterate- The return listed for the atkins slot machine is 97.046%. Is this representative of total out / total in? (From what you just said, that sounds like "yes"). Would the average return and the total return start to match after large number of spins? And finally, is the total return significantly more important than the "average" return, or does the average return have importance to it, perhaps in modeling a player's short term experience on a slot machine? (I'm thinking of this from a "designing" a slot machine perspective, which this may or may not be the right place to be asking that kind of question).

Thank you again!

In the log run, the actual return on a slot will approach the return that is calculated. This number is very important for the casino. As for the short run experience for the player, you are talking about volatility. Too much volatility, and players might walk after winning nothing on their first $20. Too little volatility and many players will get bored.

Is the win rate of a slot (the probability of any win for a single spin) indicative of a slot's volatility?

Yes, there is a correlation. Generally, if a slot has a low hit frequency, then the pays are higher and so is the volatility. If a game pays smaller amounts, but pays frequently, then the volatility is low.

That explains why peeny slots are considering the crack cocaine of slots.

Yes, my 97% figure is the ratio of "total out" to the initial bet. I think the average return per bet would amount to the same thing, but nobody ever phrases it that way.

I think the ATKINS slot machine is malfunctioning. I played it for over 40 hours last week and gained 3 pounds. WTF !
