Wait, so we can't even *mention* you-know-what in this forum? That seems... that's not the impression I got from reading other threads.
In any case, as I was saying (without mentioning the dangerous acronym), my problem with the alleged efficacy AVRT is the same problem I have with all self-help programs of dubious efficacy---lack of evidence. If we can show AVRT to have a statistically significant effect, then great! Until then, I must remain skeptical.
