Length & girth logging standards (60 seconds)

Consistent self-reported logs make trends meaningful. These are athletic tracking conventions — not clinical measurements or outcome guarantees.

When to log

• Same point in your daily rhythm every time (e.g. after waking and bladder void).
• Fasted, before mechanical work — shift workers and non-standard schedules are fine; consistency matters more than clock time.
• Log structure metrics (PLE/MRV) before starting session work on structure days.

PLE — Peak Linear Extension

• Press tracking tool to the pubic bone anchor; record to distal apex under peak activation.
• Use the same technique and posture each session.

MRV — Mid-Zone Radial Volume

• Measure flat at 50% of recorded PLE; do not compress tissue.
• Log PLE first when both are tracked on the same day.

Morning readiness (optional in self-directed mode)

• Rate morning elasticity 1–4 before loading mechanical work.
• Two or more low days in a row may signal a deload — listen to numbness, pain, or prolonged swelling and stop if concerned.

Estimated latency

• Self-reported training log only — not a clinical IELT test.
• Log after endurance-focused sessions using the same estimation method each time.
