Increased transport in resonant magnetic perturbations (RMP) H-modes reduces the pedestal pressure gradient below the Type I ELM stability limit. The RMP induces more particle transport and less electron thermal transport than expected from simple stochastic transport models. This increased transport starts during the RMP rise-time, and displays a broader resonance in q95 than ELM suppression. Evidence suggests that the transport is at first caused by a combination of neoclassical transport in the 3D equilibrium, $E\times B$ convection in the weakly stochastic layer, and fluctuation-driven transport. After the ELMs are suppressed, fluctuations increase due to Er shear changes. Optimizing these transport changes will improve the viability of RMP ELM-control for ITER.    [ Preview Abstract ]
