I think that we all practice according to our understanding, which will change over time, and will never be identical to our teachers or our classmates or others doing the same system. So it all changes somewhat, every generation, and with every practitioner. But not everyone teaches and passes it along, so many changes die with the individual and only some get passed along and become long-term.

If the method makes sense and people can relate to it and it yields positive results, then it will likely carry forward. And thus, variants or even different systems eventually form.
