The passage around this formula
Because published TopK configurations keep k in the tens to low hundreds while n runs into the millions, n k and the encoding term dominates almost entirely: 2dnT . That single approximation explains something the paper reports without deriving: convergence — the point at which more tokens stop buying lower reconstruction error — is reached later…
