+ChadScript compiles through LLVM, the same backend behind C and Rust — so it gets the same optimization passes. Compared against C, Go, and Node.js on Apple Silicon. **Median of N=10 runs**; full 95% bootstrap confidence intervals on the [benchmarks dashboard](https://cs01.github.io/ChadScript/benchmarks).

+**Statistically tied with C on 3 benchmarks** (SQLite, JSON, Monte Carlo — 95% CIs overlap). **Beats both C and Go on Binary Trees** — but loses to Node's V8 JIT which eliminates allocations via escape analysis. **Matches Go within 5% on Matrix Multiply, N-Body, Monte Carlo, and Sieve.**

+For each language, we parse all samples and compute:

+  - ci_lo / ci_hi    → 95% bootstrap confidence interval of the median
+  - samples          → full list, preserved for transparency / future analysis
+
+Ranking is tie-aware: two languages are considered "tied" when their 95%
+confidence intervals overlap, which is the standard non-parametric criterion
+for "statistically distinguishable at the 95% level." Spurious medal-flipping
+from runner jitter is eliminated because a 2-3% absolute gap between two noisy
+measurements lands inside both CIs and is correctly called a tie.
+
+For N=1 (e.g. the startup benchmark, which internally averages 50 launches and
+emits one aggregate number), the CI collapses to a single point — we fall back
+to a 5% heuristic halo around the value so ranking still works.

 ChadScript compiles to native binaries via LLVM IR — no runtime, no JIT warmup, no cold start penalty.
 
-These benchmarks compare ChadScript against C (clang -O2), Go, and Node.js across compute, I/O, and real-world workloads.
+These benchmarks compare ChadScript against C (clang -O2 -march=native), Go, and Node.js across compute, I/O, and real-world workloads.
 
 <BenchmarkBars />
 
 ## Methodology
 
-- **Machine**: Linux x86-64, single machine, all runtimes tested sequentially
-- **Optimization**: ChadScript and C compiled with `-O2`
-- **Timing**: Wall-clock time via `perf_counter` / `clock_gettime`
-- **Cold start**: Average of 50 runs
+- **Machine**: Apple Silicon (M-series, arm64 native), dedicated hardware, all runtimes tested sequentially
+- **Optimization**: ChadScript and C compiled with `-O2 -march=native`
+- **Sampling**: Each compute benchmark runs **N=10 times**. The reported value is the **median** of the 10 samples, annotated with a **95% bootstrap confidence interval** (2000 resamples, `random.seed(0xC4AD)` for reproducibility).
+- **Ties**: Two languages are treated as tied when their 95% CIs overlap — i.e. the difference between them is not statistically distinguishable at the 95% level. This prevents spurious medal-flipping when jitter produces a 2-3% gap that's inside both intervals.
+- **Cold start**: Average of 50 launches (aggregate measurement, not per-sample).
+- **Timing**: Wall-clock time via `clock_gettime` / `Date.now()` / `time.Now()`.
+
+The CI whiskers on the bars show the 95% confidence interval. A narrow whisker means the samples were very consistent; a wide one means the runtime is variable and the point estimate should be trusted less. **Bars whose CIs visibly overlap are statistically tied** — ranking between them is meaningless.
 
 Reproduce locally:
 
 ```bash
-./benchmarks/run.sh
+BENCH_RUNS=10 ./benchmarks/run.sh
 ```
