What this means
claude:haiku

D. melanogaster WGS on Genome Analyzer IIx with 5.2B bases and 37.3× coverage but 75.1% Q30 — mid-range quality for this platform. Suitable for variant discovery and abundance estimates in population genomics, though the moderate Q-score introduces noise for calling rare variants confidently.

How this grade was computed
Weighted mean of 4 scored metric(s) → 76/100

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