Goal
Verify the issue only occurs under peak or burst conditions.

Steps
1) Ask staff:

• Does lag happen only during rush?
• Is KDS responsive when quiet?
  2) Observe current load:
• Number of active orders
• Frequency of new orders
  3) If lag disappears off-peak → proceed to P-000125-02.
  4) If lag is constant → treat as different performance Trouble.

Pass/Fail

• PASS: Lag correlates with peak load.
• FAIL: Lag present at all times.
