One thing that shouldn't be ignored/underestimated about this presentation is the information surrounding diluent:
"The literature surrounding duration of toxin and its relationship to dosage and amount of diluent will be analyzed as well as early clinical experiences."
Some KOL's (Dr Jean Carruthers, Dr. Sue Ellen Cox among others) have been promoting/studying the idea that using less diluent with the same amount of Toxin increases duration.
I'd be very interested in finding out what the conclusions of this Sunday session are.
