Your point? Daniel Tammet is an autistic savant. And some people have eidetic memory. There is little relevance unless we find a method to recreate these traits in "normal" people, there is by no means any evidence that every human has latent super powers.
As a normal person having nevertheless high language aptitude, I reached C1 or very close to C1 in about 6-7 months. I say close to C1 despite reaching C1 level in a test, because I don't think it's fair to claim you have every capability for C1 as described by CEFR just because you passed a 4-hour test, in certain ways you just cheat by learning for the test. Anyway, even that was with a very generous amount of immersion, about a minimum of 8 hours a day including long hours of grammar practice. Still, despite praises from native speakers, at that time I wouldn't assert that I was fluent in speech or writing. Now to claim you can be "fluent" in 5 months just by studying 30-60 minutes a day is a bit outrageous.
I can't tell you how much our brain can really "absorb" and "retain" in one day, but there are very real limits in language acquisition after a certain age. I won't say it's impossible, but to realize your claims, we definitely need a magic pill or surgical operation / cybernetics.
