  We determine the frequency of regions of small-field inflation in the Wigner
landscape as an approximation to random supergravities/type IIB flux
compactifications. We show that small-field inflation occurs exponentially more
often than large-field inflation The power of primordial gravitational waves
from inflation is generically tied to the scale of inflation. For small-field
models this is below observational reach. However, we find small-field
inflation to be dominated by the highest inflationary energy scales compatible
with a sub-Planckian field range. Hence, we expect a typical tensor-to-scalar
ratio $r\sim {\cal O}(10^{-3})$ currently undetectable in upcoming CMB
measurements.
