Definately some sinking in the set position. you seem slightly bunched up…your initial step and hand motion looks great…now this is serious nitpicking and I am not a biomechanist, but from my observartion your first 3 steps are very solid and your body angle rises ever so slightly but starting at the 4th step it looks like you drop your angle further instead of keeping the gradual rise in the drive phase…
thats a great website by the way I like all of the tools for the videos
