> 100x is achieving something in two days, what it took an entire year before.

Reduce your scale: "100x achieves in 1 hour what used to take 1 week."

One year of work could require levels of complexity and human judgement that can't be accelerated past a certain point.

1 week of work can be reduced to an hour and some change.

The baseline engineer in that case must really be something incompetent.
