As painful as it is to admit, I've come to the same conclusion, after wasting quite a lot of time and efforts.

As Warren Buffett likes to say - "It's better to be approximately right, than to be precisely wrong"

This should be a poster in every company doing any kind of data.

I think in some other context it's actually preferred to be precisely wrong than roughly correct

maybe this is the difference between a business (or engineering) mindset of "it must work effectively, how and why it works are secondary"

in contrast with a perhaps more phillosophical (scientific? purely mathematical? reverse engineering?) study goal? in which case whether something works is secondary to having a full theory of what's going on
