The regularity theory for pluriclosed flow hinges on obtaining C^\alpha regularity for the metric assuming uniform equivalence to a background metric. This estimate was established by Streets in an adaptation of ideas from Evans-Krylov, the key input being a sharp differential inequality satisfied by the associated 'generalized metric' defined on T \oplus T^*. In this work, we give a sharpened form of this estimate with a simplified proof. To begin, we show that the generalized metric itself evolves by a natural curvature quantity, which leads quickly to an estimate on the associated Chern connections analogous to, and generalizing, Calabi-Yau's C^3 estimate for the complex Monge Ampere equation.
