SARS-CoV-2 amplicon (Illumina NovaSeq 6000). Grade C/77—96.25% duplication is extreme and dominant, rendering nearly all reads non-independent PCR replicates. Longer reads (249bp mean) offer some utility, but duplication burden is prohibitive; Q30 (83.2%, scored 66/100, weight 1) is lower than ideal, and these combine to severely limit variant detection confidence.
The C 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.
