DD has started flipping tsuks by herself, but not yurchenkos.
She had done spotted tsuks for the last few months, and only recently started doing them alone. Last year she spent months doing 1/2 ons, then just flipping to her back on a mat (not timers to a raised mat).
She started working on the RO entry for the yurchenko in earnest in July. She will compete a yurchenko timer (to candle on mats at vault height) this year, but has only done one fully spotted flipping yurchenko ever. She doesn't expect to be doing one alone on a regular basis until the end of the year. She does ALOT of entry drills.
When we go to the states, she will compete a Tsuk. But she LOVES the yurchenko.
So, a lot of drills, a lot of prep work. No chucking of skills for her.
