Firstly, you "found no real correlation" between my claim and the audio clips/score because you're deaf. You don't know what a succession of fourths is supposed to sound like: clean, distinct, with proper voicing and separation. Lettberg smears them, collapses the texture, and loses the entire point of those moments. But I suppose if you're a similarly sloppy player yourself, or just unfamiliar with what clarity and precision actually sound like, then this wouldn't register as a problem.
Secondly, appealing to "critics" and "reviews" is laughable. Most people praising her are just excited she recorded the complete works, which is a rare feat, but hardly a guarantee of quality. Being "to-the-letter" in Scriabin means nothing if you don't understand the inner logic of his harmony and phrasing. And no, dissertations don't make you a good interpreter. There's a long history of mediocre performers padding their credentials with academic nonsense. If you can't hear the basic sloppiness (rhythmic imprecision, pedal haze, dynamic flatness), then no amount of liner notes or glowing blurbs is going to compensate for that.
You say I'm the only one who thinks she butchers the 8th, but it literally took me 10 minutes to find multiple people point out her flat, uninspired, technically-flawed playing. Pic related. But of course, these don't count to you, because they're not "seasoned experts", right? What you mean is: you'll accept only the opinions that match your own.
You're defending mediocrity by consensus. I'm describing exactly where and how it fails. The difference between us is: I trust my education, ears, score, and I've formed an informed opinion through actual active listening and specific musical critique, backed by examples. You trust Amazon reviews and CD booklets.
