Trudy is fantastic and I couldn't have ask for a better teacher. My training with her was all 1-on-1 and over Zoom. Before going with her I did a lot of the self-taught material and always wondered if I was doing it correctly and it was always a mystery. A lot of nuances and subtleties that can't be explained or corrected over a pre-recorded video. Also, a lot of self doubt because there's no one to guide you.
My only regret was not being able to continue my training with her. I had just barely scratch the surface and got a taste of this incredible artform. RV is very much real and any skepticism I had disappeared.
I can't speak for the other Instructors as to their methods and style of teaching but it never hurts to ask.
