What this means

claude:haiku

Human amplicon. Good reusability (grade B) with Q30 at 85.4% (borderline acceptable, scored 77/100) and low adapter contamination (1.27%). High measured duplication (90.43%) is amplicon-typical; caveat is that mean_target_coverage (2.3x) is extrapolated and requires measured validation before committing to high-precision analysis.

How this grade was computed

Weighted mean of 2 scored metric(s) → 84/100

The B grade is a transparent weighted average. Each metric below scored from 0–100% against the published amplicon thresholds, weighted by its importance; nothing is hidden or subjective.
