SCT or PFT - New idea of weight Training

I’ve read about these two new methods of weight training, they look a little like isometrics. Does anyone have any experience with either?

Partials in the strong range can have utility for

a. improving a weak point (i.e. bench/squat/dl lockout)
b. putting all kinds of major stress on connective tissues
c. impressing your buddies/the people at the gym
d. making you think you’re much stronger than you really are

Only one of those is a useful goal for athletes of any caliber, IMO.
