At $z>5$, we find increased abundances of massive (log$\\, M_{\\star}/M_{\\odot}>10.5$) implying integrated star formation efficiencies (SFE) $\\epsilon_{\\star}\\equiv M_{\\star}\\, f_{\\rm b}^{-1} M_{\\rm halo}^{-1} \\gtrsim 0.5$. We find a flattening of the SMF at the high-mass end that is better described by a double power law at $z>5.5$.
