What this means
claude:haiku

This environmental-sample amplicon sequencing from Illumina MiSeq delivers broad microbial/eukaryotic community profiling (20 million short reads, 10 GB bases) at high per-base accuracy (Q30=90.5%)—depth and quality support precise operational taxonomic unit resolution and abundance quantification across diverse environmental niches, enabling biodiversity assessment and ecological-association studies.

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

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.
