It's a nearly meaningless difference. You won't even notice that extra failure. The feat itself is far better than any +1 to a stat bonus.Exactly. The feat given by the background is objectively weaker because of this, and her we are not talking about a class, where you can choose a different one, but a feat that is tied directly to the background.
Morover though, while you fail once "more" out of 20 attepmts, your overall effectiveness decreases by around 10-20% because that failure that was flipped was one of only a subset that would have suceeded.
And that 10-20% increase in failure is also meaningless. It sounds good until you realize that the difference is so small you won't be able to notice it.
It's like those studies that say your chances to have a heart attack go up 100% if you do X, but then it goes from .0000001 to .0000002.
