It seems to me that there might be a bit of change as the distance increases. It is not too difficult to be well over 2:1 (or 2.141:1) with short distances because the 3:1 ratio of 'steps'. However, the further the jumps that more the landing forces and the more the initial speed matters, and the attendant loss of speed over the multiple jumps.

there is a lot of skew because wind ( max 2m/s ) can affect lj & tj by both ~ 2%, which shows up much more dramatically in tj ( e.g.17.00 with 2m/s = ~ 17.34 )

I think he was implying American kids are fat. That was so random.

I've got almost 100 on my track team. Not one is obese by any standard. Most of them are downright skinny. My boy PVers, good athletes, are 115, 120, 125, and 160 (6').

Light weight does not always mean not "fat". When I coached HS, I had a real slow thin girl. It all made sense when her body fat measured out at 30%- she had virtually no muscle, and was "fat". That was an extreme, but clearly makes my point.

That's what I refer to as a 'jiggly girl'. I have had a few (zero boys) and they're easy to spot on the first day of practice. I always steer them to the distance coach, not just to get rid of them, but I think that's what they need most of all, conditioning.
