Hangglider Tailwind Landing Willswing Sport3

Another fine day of flying with my Sport3, first weak thermals at Altes Lager 52N 013E, but also changes in wind direction due to thermal activity. Questioning my timing of the flare, looking at the recorded ground speed of the Gopro, it seems as if some tailwind component contributed to the bungled landing and my inability to run it out. All other landings so far with the Sport3 have been very easy. This was landing No. 7 of the year. - Comments welcome.

I fly a S3-155 as well. One thing that I have found for good landings is this: Having an established roundout height. This height is about 0.6 meters (~2 feet, about the height of a kitchen table chair) I pull in with quite a bit of speed and round out at that height. Once at that height bleed energy down to trim at which point I move both hands up to the flare position near my ears, with my back arched to be as upright as possible. From there I'm only waiting on one of two things: 1. the input to the glider starts to feel "light" OR 2. The glider sinks below my roundout height. Both indicate that I am out of energy which will cause me to hit my flare very hard. Easy rules I follow in the flare are these: If ground moving fast, flare fast, if ground moving slow, flare slow.
To apply this in your situation you hit the roundout at 0:14, and the height looks about ok, but at 00:16 you adjust your grip and the glider doesn't pitch up (indicating trim) and at 00:18 the glider is falling out of the sky (which means you're past your flare window). At 00:18 you do your flare but it's not nearly strong enough to stop. The wheels save you from any serious damage or injury. Not a bad result considering.
Possible things to help you in the situation: Start your pull in higher and pile up even more speed so that it extends your ground skim and gives you time to get sorted. If you have your roundout height nailed and body position upright you have a shot at running it out if you miss your flare window. You can even run+flare. While it does look like you had a bit of tailwind component if your feet were under you and had a stronger flare you had a chance at running it out, as it was I think you made a good choice in pushing the bar away as you rolled out to bleed speed.
I've had to belly land too because of a strong thermal driven wind shift, sometimes all you can do is throw the bar to avoid swinging through. Good luck! Open to any counter-comments.

Thanks for your comment and advice. I also think that I was too late to flare. Concerning the other suggestions, I think we delve into the 2 basic existing techniques for landing (go to the downtubes early or late while in ground effect), both having advantages and disadvantages imo. Here in Germany the present taught technique is to change to the downtubes on final combined with a progressive flare. This is the technique I favour, even though much less elegant.

Is it the control bar that height or your feet?

Next time flare like you mean it. I've done a few down wind no step landings in my 44 yrs of Hang Gliding.
