I’m trying to summarize the theory behind choosing right or left S, and it is hellish, because not only are there lots of variables to consider, but also the rules conflict each other and an order of priority has to be determined. To avoid reinventing the wheel, I’d like to know two things.
1/Are the rules for right/left S consistent across all series?
2/Has a flow chart or “decision tree” ever been made for this? Because that’s what I’d like to (try to) do.
