I am here providing an anecdotal story.

Zurich Switzerland -> Austrian Alps

Heavy traffic, incidents along the road, gridlock ...> Waze got us there FASTEST.

"ATTENTION" "WAZE HAS JUST FOUND A FASTER ROUTE".

Competed against iPhone & Google Maps.

Same way return drive. ... So two data points I guess.

Austrian Alps -> Zurich

Plus ... I use it daily... So three data points then.

It's entirely possible you're right, but I don't see how on any individual trip you can assert any solution achieved the best time, unless you have 3 different drivers to take each proposed route (and even then, there's enough variability to make it suspect unless you do it over a long enough period of time).
