@cramoisi I might not answer this very correctly, as I don't know a lot about the RR (never did it), so I don't really know which of these skills are in the RR and which are not. I tried to divide my skill tree into eight subtopics:
- Core strength(ish)
- Pushing strength
- Gymnastic Rings Skills
- Pulling strength
- Bicep/Hefesto(I couldn't really fit it into anything)
- Back Lever(not quite pushing or pulling IMO),
- Handstand strength/balance
- Parallel Bar Sits/Reverse Planche(once again, an argument could be made for putting the Reverse Planche into the Pulling strength category)
If I am correct in my assumption, this way of categorizing is not the same way things are organized in the RR. This means that my skill tree is more of a broad list of goals that you could set yourself to achieve. I think it might be a good way to organize training for certain skills, but it is probably not the best guide if you are looking for a way to learn the progressions themselves. In that regard, this would have to be considered a standalone, not in direct connection with the RR, and the RR would be your source for progressions and routines.
As stated in my first sentence, I think that many of the skills listed in my skill tree are not in the RR, mainly because they are quite frankly "insanely" hard to achieve and probably not relevant for somebody who has set themselves to become very good at the basics, someone who is understandably not willing to dedicate their whole life to training these skills.
To sum up my messy paragraph organization:
This is not directly related to the RR and should mainly be used to visualizing the way to your goal, in case it is not included in the RR. If you stick to the RR this skill tree would probably never be of much relevance, but if you ever decide that the RR doesn't include a certain skill you want to learn, the tree might be a good way of developing your own training program.
I hope my writing was somewhat understandable and that I answered your question.
