There seems to be a new wave of 'countertop HP' on the assumption that higher temps=more fluidity. I'm not quite sure about that though. I've gotten pretty fluid HP with a low temp method. Taming a volcano is quick and exciting, but as you mention not the safest option and I'm a bit worried about newer soapers thinking they need a volcano to get a fluid HP soap.I also wonder why anyone wants to heat soap to the point of a volcano which can be dangerous? I know there was/is a soaper that hp's this way but it is far from necessary. When I do hp soap my soap is usually done in less than an hour and once it hits thick trace I do not stir again.
