It is a not a variance in style, it is a huge variance in physical difficulty.
If a transfer of weight is executed differently in one style or dance compared to another then there is a variance in style or dance.
"Huge variance"? Oh, come on. Like a Fox Trot heel turn is so much different from those in Waltz and Quickstep that they require different training regimens.
Still waiting for an answer on that question about your having an amateur partner.
