Sentence composition guidelines

[Justin Webster]

When constructing the Sentences and Arguments in a Debate, there are a lot of different ways to do things.

For example:

1. A Conclusion could be stated "Some believe that X is True." or "Many believe that X is True." or simply "X is True."
2. A certain Premise could be stated as "If X then Y, and If Y Then Z, Therefore If X Then Z", or the same Premise could be split into a new Argument with 2 Premises and a Conclusion, or it could be simplified as simply "If X Then Z".
3. In what circumstances is it better to leave "qualifying" or "adorning" grammar and content in a Sentence? E.g. "Given X, Y is True" vs. "Y may be True" vs. simply "Y is True". When is it an advantage (if ever) to condense Sentences into complex, single Premises/Conclusions vs. deconstructing them into entire complex Argument diagrams?

Are there any argument diagramming "best practices" or guidelines when it comes to the wording, structure, composition, and content of Sentences (whether Premises or Conclusions), and the use of Conditional language, Qualifying language, Copulas/Copulae, etc.?
