The AHT value indeed went down 3 minutes below the average, which is generally a good thing so long as you are doing everything well still. All outliers get checked and mine was the lowest. I was honest about the tool, including that it was offline. Their supposed policy was no personal tools and as it was during "probation" (first 90 days in Ontario), they could fire without cause, and did, immediately.

A good business would have promoted you to the dev team so they could reduce that metric for everyone.
