Just a theory, ironically enough I was actually thinking about this today at work (shut up, works boring) and I'm wondering, the static load test pulls the wing end plates straight downwards right? What if the wing doesn't flex straight downwards? Maybe they flex on an angle, down AND backwards? So they only flex when it has windspeed of 150km/h plus pushing the wings backwards as well as downwards with the downforce do they flex, rather then just straight down as in the static load test???
