I see again & again in your posts that you recommend the Wright Calculator.
OK maybe for professionals in this field - but for lesser mortals with maybe a science degree, engineering degree or similar, well frankly this calculator is utterly unconvincing.
First, we are all trained not to blindly calculate without a good understanding of the assumptions that may be involved, & that always we should have the means or experience to judge the result as acceptable or not.
Now I have looked at this calculator & conclude it is totally inappropriate for use by anyone not suitably trained or supervised. This clearly includes many of the people to whom you refer this site & it includes myself.
In fact I think for the purpose it was probably intended it is archaic in design (pathetic GUI) & lacking the guidance notes or even the symbol definitions you might expect to find.
I have not studied all Prof Wrights tuts but some of his other posted material suffers similar shortcomings.
