Turbostat and sar telemetry data occasionally contains single readings that are orders of magnitude too high, compressing useful data into a tiny band at the bottom of HTML charts. Add percentile-based outlier detection that sets a hard Y-axis max when the actual maximum exceeds P99 by more than 50%, keeping charts readable while preserving outlier values in tooltips. JSON and XLSX outputs are unaffected. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
