To clarify I was laid off few weeks after the feedback. I was on the job for a few months. I asked for the reason, and it was indeed the performance. It was just the diagrams in the original article that reminded me of this. It just didn't make any sense to me that one would "just solve" a problem at hand without considering other options. But in my (15 years of) experience the "pi factor" is indeed quite accurate as there is always something surprising that comes up along the way, be it specification changes or technical issues.
