The amount is "correct" so as long as it is somewhere among the spectrum of probability, which is already in your case. The game being strategy doesn't change the fact that this particular item is based on a chance. My personal thought is that if you are "expecting" a specific result when it comes to probability, then you set yourself up for disappointment.
I fully understand what you are saying but from my point of view these aren't "fixes" for something, they're suggestions to change behaviour. I also don't think you will find many people who are happy with their number of relics for the simple fact that generally when people are happy they just continue playing. When they're not, they speak up. I know because I've had weeks with many relics (more than "expected" by that %) and I didn't tell anyone about it. But then weeks come when I have less (less than the "expected" by that %) and you will then find me complaining about it to my guild or friends.
