Description
We show that the Borel resummed perturbative contribution of the stochastic
perturbation theory and dimension-4 gluon condenstate can acccount for the
average plaquette data, and the resulting gluon condensate of the
$\text{SU}(3)$ pure Yang-Mills theory is determined to be
$\langle \frac{\alpha_s}{\pi} GG \rangle\approx0.13\,\, {\rm GeV}^4$.
A critical review of the existing procedure of renormalon subtraction is presented.
