I edited my post to say what my preferred passes would be
Here's my reasoning:
1. A roundoff is a big ugly complicated frankenskill. It uses the entry of a front handspring, the support phase of a cartwheel step-in, and the landing of a backhandspring. Each of those skills is much less complex (not necessarily easier, just less complex), and if you teach all those skills first, then the athlete already has an intuitive feel for what a roundoff should feel like.
2. A roundoff that does not connect to a backhandspring is an incorrect roundoff (at least until you hit the upper levels, and start doing RO-3/2-punch front). The entire purpose of a roundoff is to turnover and generate power for a BHS, and you can't really do that without actually doing a BHS. Therefore, it shouldn't be in a compulsory routine in isolation. But also, standing BHS-BHS should come before RO-BHS, because the lack of long-axis turn makes it simpler and easier to train without going crooked. Once they understand the connection between BHS and BHS, turning that first BHS into RO is trivially easy, because they already know what the snap and connection should feel like.
3. Power and speed cover up mistakes. Doing skills slowly makes mistakes much more obvious, and forces much better technique. Therefore, they should learn to accellerate within a series of backhandsprings from a stand before they should learn to add power with a run, a hurdle, and a roundoff. Delaying the addition of that speed and power as long as possible forces better technique.
