Let me put it this way. When I finished my doctorate, I had to test the computer code against the published work of five or six other groups, whose results spanned a period of decades.

Only when I was able to reproduce their results, to three or four decimal places, was my code deemed bug-free.

it would be so much easier if they gave you their work, with that many groups, who knows how accurate their measurements were unless you had done a study of their samples.
