How Independent was the Independent Audit?

   I find the story saying an FBI audit found only "minor" errors in FISA applications of importance. An independent audit had previously released a scathing rebuke of the FBI for the FISA mistakes. Now, with the new audit, there is good reason to believe the errors were not of great consequence.
  One significance of all this, is it make one wonder at how independent the independent audit was. Was it influenced by the Trump Administration to reach a verdict pleasant to the president?
