WHAT BACKFLOW TEST READINGS SHOULD I HAVE?

QUESTION: I have a test report showing test values of 3.6 PSID across the first check, 3.4 PSID across the second check and 2.0 PSID relief valve opening. When I entered these values into my backflow tracking program it showed this as a failed test but the tester marked it passed. Can you explain?????????????????? BACKFLOW COMMITTEE REPLY: Your software flagged this test as FAILED because the first check valve reading must be above the relief valve opening point and ≥ 5.0 psid.
