Well, I am not sure either. I just find it interesting that Tiger Woods - the Worlds #1 Golfer - failed to dig down enough. With his experience he should be able to do that in his sleep. I also though it might be a very pedagogic piece when describing Drive Loading and Float Loading. But that's just me and I am not authorized...

Also I think it may be interesting from a machine point of view - and I'd like to hear the right answer.

I'd say he is not Drive Loading as that would cause his right foot to break through already on the backswing. Since his support breaks on the downswing I'd say that is proof of Float Loading.

I think Tiger subconciously applied Float Loading since he felt that Drive Loading might break the sand already on the backswing.

As I said I am not sure. But I think someone with excellent machine knowledge would be able to give the definite answer.

From what I've understood:
- Drive Loading occurs early
- Drag loading is from the top
- Float loading occurson the downswing.

...and during the loading action force goes down your feet.

With that in mind it should be possible to determine what type of loading he is using by studying the timing when his support breaks.

If loading action are not the cause of force going down the right foot I need to know it anyway.
And I also need to know if my reasoning regarding loading timing is valid.
