| Result | Meaning | |--------|----------| | | O(1) (just two probes). | | Expected insertion time | O(1) amortized, because the probability of a long eviction chain drops exponentially. | | Space utilization | Up to ~50 % load factor for the simple 2‑choice version; with bucketized variants you can push it to > 95 %. | | Failure probability | With tables sized at (1+ε)·n (n = #keys) and truly random hash functions, the chance of needing a rehash is ≤ n⁻³ for ε≥0.1. |

Understanding these dynamics helps us see why a seemingly trivial term can have outsized effects on public discourse. cuck4k
