Regarding the 100% accuracy thing, really, nobody cares. Would anyone play most of Chopin's music perfectly in time (even the appoggiaturated parts)? Probably not, because it's insensitive to the style and emotional portrayal of the music. Here, Sorabji writes complex polyrhythms, but the groupings are there for purposes of emphasis and not perfect timing. In fact, it sounds quite awful to play them perfectly.
If you're implying that I intentionally left out notes in the recording, then I didn't. If you're referring to me unintentionally missing some notes or playing the wrong ones, then sure, here and there it happens. But still, as long as it doesn't detract from the musical concept that is being projected, nobody really cares for this kind of music.
Also, why are you not willing to watch a 20+ min video? The OP video Gulistān is 35 minutes long.
Also, the connection between memory and sightreading is just a vague summary of what I talk about in the explanation video.
I'm trying to spark your interest here, but if you feel you know everything there is to know about learning music quickly, then I'll take your word for it (and don't know why you even asked in the first place), and expect to hear some recordings done in an exceptionally short learning time as well.
