Improvements normally come from more granular observations.

My son is learning swim, our new target is to reduce 10% time, it sounds like unrealistic and have to wait for him to grow up and hopefully everything happens automatically for the bigger boy.

I discussed with him and compared others’ videos, we located several places that we could crawl some time, jump start, turn, streamline, each of them might give 1 or half seconds, looks like there is a concrete 5% space we discovered just with this first exercise - look closer.

I have been proud of my technical strength in e2e dynamic system scaling, reliable, and performance per cost efficiency. All started with good dashboard, then more granular observations.

0-1 requires innovation, paradigm shift requires learn and speed, crafting an existing system, normally just need someone persistently working on small granular improvements.
