Hey Tom,
I did not say that everything that you get as results even if the data are not perfect is useless, not at all. I just wanted to emphasize that – maybe also because the images you can generate are so impressive – you should always be aware of exactly how good and how accurate the information is, or is not. Of course you can illustrate and recognize a lot of basic information about material twisting even with only approximate data, I didn’t want to diminish that. But I have been working with data analysis and statistics for a long time, and I have found that just a curve in a coordinate system can impress many people to confirm something that someone claims just because it looks like that. I am very sensitized to this. I was also just referring to the example above, which was not so inviting to agree with, given the data I was shown about it.
Haven’t followed the youtube link yet but I will do! And I believe you if you say “The members of the forums whose builds I follow know a lot about their materials”, you can point me to interesting information at any time, I appreciate that as you know 
Indeed. As I wrote in the other thread.
