Does more volume mean deeper claims for Test?

Each dot is one of Test’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Test’s own 3.6 claims/patent is at or below the 12.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
