What this means

claude:haiku

Human amplicon sequencing (MiSeq). Grade-B marginal (82/100) limited by Q30=84.6% (scored 73/100) and extreme duplication (92.88%), typical of amplicon PCR bias, both measured. Target coverage (8.1x, extrapolated) is low and requires independent verification. Marginal for quantitative work; reuse demands high confidence in assay sensitivity.

How this grade was computed

Weighted mean of 2 scored metric(s) → 82/100

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.
