4. Update Action Logic

1. Modify the D2 distributions in the action logic located in Pass Inspection.

Each time the same entity enters the Pass Inspection decision, the chance of success increases. The current settings give the following results: Pass number 1, 2, 3, 4 and 5 have a percent successful of 50%, 75%, 90%, 95%, and 100%. The “PASS” or “FAIL” values for the a_Dir attribute, determined in Pass Inspection’s action logic, are tested in the Conditional routes leaving the decision.
