I agree, I think RT is generally just low dose and/or bad prep due to being unsure of what you're doing. I drink every day but if I do take a day off I think I've got enough kava in my system that I can still feel it keeping me calm the day after not drinking. In the past I have had time away from drinking kava, a few days at a time and I did notice that it wouldn't always hit me in the same way the first day back but not sure I would say that was RT again. I think the best way to explain it is if I've been drinking multiple days (or weeks!) in a row then it doesn't take a lot of kava to get me somewhere nice, I'm just topping myself up. If I haven't drunk for a few days then my levels will be a bit lower and it might take me a bit more to get there or in other words my regular dose won't do what I expect it to do. That's logical at least.
