  We present an extensive comparison between the statistical properties of
non-hierarchical three-body systems and the corresponding three-body
theoretical predictions. We perform and analyze 1 million realizations for each
different initial condition considering equal and unequal mass three-body
systems to provide high accuracy statistics. We measure 4 quantities
characterizing the statistical distribution of ergodic disintegrations: escape
probability of each body, the characteristic exponent for escapes by a narrow
margin, predicted absorptivity as a function of binary energy and binary
angular momentum, and, finally, the lifetime distribution. The escape
probabilities are shown to be in agreement down to the 1% level with the
emissivity-blind, flux-based theoretical prediction. This represents a leap in
accuracy compared to previous three-body statistical theories. The
characteristic exponent at the threshold for marginally unbound escapes is an
emissivity-independent flux-based prediction, and the measured values are found
to agree well with the prediction. We interpret both tests as strong evidence
for the flux-based three-body statistical formalism. The predicted absorptivity
and lifetime distributions are measured to enable future tests of statistical
theories.
