I see. Well that's pretty scary to have untrained/unmentored people doing performance testing. Imagine if instead of teaching and mentoring new drivers we just put them behind the wheel. The consequences aren't as bad in performance testing but you get the idea haha.
I'm just saying this because I wasn't trained properly and for the first year I produced some test results yes, but they were completely invalid because I didn't design the load correctly. So we produced some numbers and went with them, but I didn't know the numbers weren't valid until I learned more about performance testing.
