They are accurate because they are calculated manually by my membership, counting all the spin wheels made with the relative amounts.
Tickets do not count towards the return on investment, only satoshi, points and any special prizes, also because there is no guarantee of winning in the lotteries, so they are not part of the ROI.
Individual results will always vary and may end up being worse or better than what is expected according to probability. Your results are only a statistical sample. To determine the specific odds of getting each prize we can look at
the prize table. The only exception is the Rolex prize which has much lower odds than 1 in 1,000,000 because of how they round the result of the provably fair formula. The odds were not always the same, so depending on what data you are using in your sample, it might skew your perception of what the odds are today.
The table only confirms what I said, we are talking about mathematical probabilities, not abstract things, most of the spins were always 50 sats/points/tickets, with a FUN price of 50, today the spins are 17/18 sats/points/tickets with a FUN price of 4, so the site should pay up to 4 times more than what it was paying, and it is no longer sustainable, especially that for now the investments on FUN are blocked.
Let's see if they can come up with something good to unblock the situation, or clearly the FUN will be short-lived.
