Make the comparison reproducible

Fix materials, geometry and observations around both candidate layouts.

Joint duty
What to record: Load direction, reversals, peel or shear tendency
Project detail: ____________________
How to confirm: Mark force arrows and restricted zones on the drawing

Material stack
What to record: Tape, panel, backing, folds, coatings and layers
Project detail: ____________________
How to confirm: Use the same conditioned lot and lay-up for both

Stitch geometry
What to record: Pattern dimensions, rows, orientation and edge distances
Project detail: ____________________
How to confirm: Provide the program or a scaled stitch map

Sewing inputs
What to record: Thread, needle, machine setting and reinforcement
Project detail: ____________________
How to confirm: Record the production-intent setup for each set

Grip and free length
What to record: Clamp faces, spacing, alignment and tail allowance
Project detail: ____________________
How to confirm: Photograph each mounted specimen before testing

Acceptance evidence
What to record: First damage, seam movement, peak, failure mode and location
Project detail: ____________________
How to confirm: Use one illustrated results sheet with buyer-defined limits

Neither layout is universally stronger; approve a specific joint and test method.
