What this means
claude:haiku

Human amplicon survey from an Illumina HiSeq 2500 with 944 million short reads at 98% Q30, generating 127 billion bases. The very high quality and massive read count enable ultra-fine resolution of human microbiota structure and rare variant detection.

How this grade was computed
Weighted mean of 2 scored metric(s) → 99/100

The A 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.
