I apologize if I offended you in any way. I did not call you stupid, I made no mention of your intelligence and I did not expect an instantaneous “roll”. I assumed you did it over time and I was just trying to say it’s a moot point to say you want to end at the same spot you started if you do any rotation for 360 degrees. Expressing my confusion is not an assault on your intelligence and I never called what you’re doing a “simple” roll. In fact I just provided an answer to your question and stated that my solution was a “basic” system. The only time I used the word “simple” was to describe the complexity of the timeline I used. You do understand I’m trying to help you and giving you my time for free. Why you are getting upset over this is beyond me. That being said, I will stop trying to offer solutions. Perhaps someone else will be better at understanding you than I.
