Past inspection readings (Jun 2024 – Nov 2026) and the proposed interim QC tension limits. Limits are derived from past readings, not a manufacturer spec.
Bar label shows the most-used strap code. Bar = proposed min to max (10th–90th percentile of past readings). Tick = target (median).ConsistentWide spread (over 40%)
Each dot is one inspection. Red dotted line = linear trend; shaded lines = proposed min/max for that model and strap where available.
Spread = (upper − lower) ÷ target. Above 40% means no consistent test setting.
