  We compute one point functions of chiral primary operators in the D1-D5
orbifold CFT, in classes of states corresponding to microstates of two and
three charge black holes. Black hole microstates describable by supergravity
solutions correspond to coherent superpositions of states in the orbifold
theory and we develop methods for approximating one point functions in such
superpositions in the large N limit. We show that microstates built from long
strings (large twist operators) have one point functions that are suppressed by
powers of N. Accordingly, even when these microstates admit supergravity
descriptions, the characteristic scales in these solutions are comparable to
higher derivative corrections to supergravity.
