"Infallible" is surely an absolute, a binary condition, and means never making a mistake, never being wrong.
As soon as you make a single mistake you are no longer infallible.
Qualifying an absolute position isn't great English, I think, but it is quite often used in a world which seems to increasingly ignore such rules.
How often do you hear "very unique!"?
But would anyone misunderstand you if you use "nearly infallible"?
No, and that's probably the most important thing.
I would agree with you there - it isn't necessarily something that should happen, but it is commonplace just the same. "Nearly Perfect", "Nearly Infallible", "Almost Perfect", et al - technically speaking, using a qualifier on an adjective would defeat the adjective at hand, if we wanted to deal in absolutes.
This is what I said in #6, but Kittamaru wants it his way or highway or James way.
Cute, but wrong - what I
want is accuracy. I (and others) have grown rather tired of folks such as yourself attempting to use obtuse pedantry to distract from having to actually defend a claim that you made. In this instance, the phrase "nearly infallible" is a perfectly acceptable one to use, despite what you may wish.
You referred and quoted dictionary for "perception".
Time to refer back to your dictionary, pl pay heed and see the meanings of infallible and fallible. You should realise that "fallible" is not deterministic or binary (as baldee referred) but infallible is.
I quoted the dictionary for accuracy - your determination to try and make this a matter of perception is laughable.
Additionally, infallible and fallible both trace their root meaning back to fal, meaning to fail or deceive

to deceive.
Common FAL- words include

fail,
failure,
false, and
falsehood.
More esoteric FAL- words include
fallibility.
So, if you wish to admit that:
That's right, fallible has degree associated with it.
Then that is an admission that infallible has degrees associated with it.
Indeed, several dictionaries would agree:

infallible
"Fallible" means capable of making mistakes — or, easier to remember — capable of failing. Infallible means exactly the opposite — incapable of failing.
This word is often used to describe human capacity for error — no one is infallible. And yet, we are able to be infallible in certain ways: children are infallibly curious, teenagers infallibly hungry. Interestingly,
infalliblederives from the Latin
in- "not" +
fallere "deceive."

The most prolonged mathematical reasoning, and the most intricate formulae, were given with almost
infallible accuracy from the resources of his extraordinary memory.
These had been sacred to almost a hundred generations of men, and it was difficult for the eye of faith to see them as other than absolutely
infallible documents.
It would seem to me that quantifying fallibility or infallibility is an acceptable and common occurrence.
At this point, I believe the onus is on the other side to show or prove that it is unacceptable, or otherwise sows such confusion as to be inadmissible in debate.
