Yesterday people asked if rippon jumps can be "easier" than normal jumps and the answer to this isnt straight forward but the physicist in me needed to give as detailed an explanation as possible. What makes a rippon jump harder than a normal jump is that to hold the position straight and strong rrequires more core strength than a normal jump since the position is longer it makes it naturaly less stable and can make jumps that tend to tilt (Valievas 4T for example) more tilted.
On the other hand if you time it correctly the uppwards movement of the arms at the takeoff can help give you extra height (compare with high jupers raising their arms when they take of in atheletics). Note that is this isnt timed right it has no effects raising your arms before takeoff or after takeoff will have no positiv impact on the jump (only a slight negative effect on jump height).
The last point has to do with rotation position. As im sure all of us know a tighter rotation position gives faster rotation. There is a term for this in physics called moment of inertia that measures how easy it is for a body to spinn. The essence here is that you want to move your weight as close to the axis of rotation (draw a straight line through your fett up through your head) as possible. This is why really skinny people often rotate faster since their wheight is closer to the axis (unfair but true). Science has shown that the most Ideal position for rotation is feet crossed, butt and tummy tucket as straight as possible and arms streched above the head with arms as close to the ears as possible with the hands together. This is the deffinition of a good rippon position. The normal rotaion position is the secon best position for rotation but the difference between the two isnt huge. The worst imaginable position is actually a camel position with the arms streched forward this is why camel spinns can often be verry slow.
So to sum up a good rippon position can give increased height and faster rotation but it requires more strength primarily in the core to hold it.

To me it looked like the fitting was fine but probably Sasha wasn't used to the lower cut in the front. Generally, I wouldn't call her dresses disastrous. They are pretty ok, especially for a season like that..
