those are the most _basic_ points you need to understand about CMOS staking ("giving birth to new coins"):
1) The more coins you have in your wallet, the more often and reliable you will stake coins. This is called network weight.
2) Staking is always a gamble. Some times you will get a stake every four hours, sometimes it will take a litte longer. Is your network weight high, you will more reliably stake every 4 hours.
3) Currently, you get 4.0xxx CMOS as staking reward.
If you can hit stake every 4 hours you are one real lucky fellow or you are holding a massive amount of cmos coins on your wallet.
i got 700+ coins on my wallet and my last stake was 2 days ago and i already consider it lucky
