We study supergravities with "enhanced UV divergence cancellations". We show that all these cancellations are explained by a simple dimensional analysis of nonlinear local supersymmetry (NLS). We also show that in all cases where E7-type duality was used in the past via vanishing single scalar limit (SSL) to explain/predict UV cancellations one could have used dimensional analysis of NLS. The SSL constraints predict in d=4 loop order L less or equal (N-2) for UV finiteness, dimensional analysis of NLS predicts L less or equal (N-1) for UV finiteness, including enhanced cases like N=5, L=4.
