Phillippe, the kind of blending being talked about by D. Orange, Mike S., and Dan Harden etc has nothing to do with the vids you showed.
The blending happens "in your body," and has little to do with timing etc.
in the body ?????
so if i get you right kemosubi no tachi and the awase is not blending
what do you mean then ?
The physical expresion of blending is always going to be taking some sort of mesure and distance. the end result of that blending is not really relevant to the blending in itself.
you can't blend on you own, you alway blend with something.
and it is as much mental as it physical.
