  A combined analytic and computational gyrokinetic approach is developed to
address the question of the scaling of pedestal turbulent transport with
arbitrary levels of $E \times B$ shear. Due to strong gradients and shaping in
the pedestal, the instabilities of interest are not curvature-driven like the
core instabilities. By extensive numerical (gyrokinetic) simulations, it is
demonstrated that pedestal modes respond to shear suppression very much like
the predictions of a basic analytic decorrelation theory. The quantitative
agreement between the two provides us with a new dependable, first principles
(physics based) theoretical framework to predict the efficacy of shear
suppression in burning plasmas that lie in a low-shear regime not accessed by
present experiments.
