What software is perfect? Every software, famously Microsoft is in perpetual development stage, surely bugs in every software ever made.
Does a part come out "better" with the software, I don't know, but I believe yes, how much "better", is the question.
The only way to prove the cost/benefit equation is by sales of the product to people who think it is. I believe Sigma problems are on the sales/marketing side, and either mispriced, or I'm wrong and it doesn't work.
Maybe it doesn't work? idk
hold tiny position.

The software would not continue to be in a beta test mode if it were commercially marketable....at least that was how it was done when I developed software.
