3 is not related to using git in any way. I’m not really sure what you mean in 4. I didn’t mean making a lot of changes, I meant that you should not wait with committing until you have a finished feature / fix / whatever. Commit after each refactor, commit after adding a new testable unit. It’s always better to have more checkpoints. If your team does code review, they will appreciate atomic commits too.
