There is always a better solution and improved methods, but as an engineer I can decide it is converges or not (because I have experience which values right and which aren't) and 12 steps are really efficient. After three steps it converges for three significant figures which is good enough for a pressure drop calculation.

But, OK, new methods are always welcome.

In the evolution's tree the engineers and scientist sits on different branch and that is so right otherwise nothing would ever be built
