Yeah, it's all good Rob. AVRT's as old as the hills, but seems like it came more intuitively to some folks than others. I wonder if the difference in our experiences is an example of that? In any event, that brings me back full circle to Trimpey. Whatever criticisms I might have, his articulation of these techniques brought a new level of confidence and contentment to my recovery. Maybe I would have reached that place anyway, but I feel his handiwork sped things up at the very least.
