It generally agree. However, Ceh & Alekna do not have a wide sweep leg after their initial 180. They stick their leg out the back of the circle and quickly transition to a “tighter” sweep as they come out of the back. Their foot is below their knee after 180. I suspect this helps them set up their rotation a little quicker.

Both of them try for a much higher orbit than you achieve here. You can see Aleknas hips rise out of the back before lowering in his power position. He uses that lift to throw his right arm high into his orbit. I think you’re closer to their technical model than anyone with a wide sweep and might want to incorporate their finer elements.
