If strict adherence to set instructions doesn’t sit right with you, then don’t adhere to them. Twist it to be used in whatever way you feel is best. The end result may not be what any instructors might have wanted you to get out of it, but the point is ultimately to get something out of it. I’ve always approached lectures, exercises, and means of training with the idea that they are meant to serve me. Whether it’s as their creators intended or not.
On the other side of that, I’ve long since learned the benefits of mastering something – skills, techniques, etc. – ‘properly’, but basterdizing these things into something I feel more in tune with or that I like better is always a possiblilty. It’s part of what has often made the teachings from one Sith to another so diverse. No one feels bound to honor the intent of the teachings from Sith that have more experience, or that were around long before they themselves were.
That is, of course, different from when you’re involved in a one-on-one training arrangement. If you aren’t looking to learn something via the manner a more experienced practitioner wishes to teach it (more or less), then there’s very little point to it. But in terms of independent and solitary study… I say be mindful of the possibilities. If you come across material that seems like it’s to much to handle as is, or that resonates in spirit but not quite in the details… play with it.
