Just keep spinning every day.
English is not my mother language, and I’m not good at it either. So it will be a bit hard for me to explain the difference between normal (Gauss) distribution and real distribution.
And I guess you’re not a math freak either so here’s a simple example:
You play heads or tails with a coin and tho there’s 50-50% chance of each result, each spins are independent events therefore the results will not be the expected H-T-H-T-H-T…, they will come in arrays (masses?) like 4H-3T-2H-8T…, and there’s equal chance that in 100 spins the first 50 will be H and the second 50 will be T, due to independency.
Your daily Oracle spin works same way, which means you won’t spin a nymph in every 30th day (I don’t know the exact chance for nymph spin), it’s more probably that you will win 3-4 nymphs in a week, and than nothing for months.
If you want to model it search any "play for free" roulette game in internet and start spinning. There’s 1/37(with zero) chance for any number to spin. Choose a number, and spin 365 times which will model „one” possibility for a year, or do more if you want. If you hit your choosen number its like you win a nymho. You will see that you wont spin your number in every 37th spin.
In (very) long term small chanches will be normalized, so after 1000 years of spinning every Elements player would hold the same (big) amount of nymphos. ???
