Turbulent Wingsuit BASE, worst flight ever

Action starts around 1:34. Had a very strange experience recently. About 3 seconds into my flight I almost got flipped on my back and continued to get buffeted by "turbulence" for a large portion of the flight. I put turbulence in parenthesis because I'm not sure what exactly caused it, either environmental conditions or the pilot(me). A similar thing happened two weeks ago from the same cliff with another experienced jumper. It was not super windy, though conditions where changing at the time I jumped with the winds having switched about 180 degrees in the past 10 minutes. Who knows, perhaps I was too stiff as I was trying some different techniques and perhaps need to relax more. I did notice that towards the end of the flight it looks like I have become slightly head high, but not sure if this is just an illusion. Next flight went much better going back to the basics and letting the suit fly itself. Also the first jump with the foot mount cam, nice angle, really like the view. Will be fun to get a really solid flight on video from this view.
