Query: Reconciling the FOPT and CIPT Predictions for the Hadronic Tau Decay
  Rate   In a recent work it was suggested that the discrepancy observed in the
perturbation series behavior of the $\tau$ hadronic decay rate determined in
the FOPT and CIPT approaches can be explained from a different infrared
sensitivity inherent to both methods, assuming that the major source of the
discrepancy is the asymptotic behavior of the series related to the gluon
condensate renormalon. This implies that the predictions of both methods may be
reconciled in infrared subtracted perturbation theory. In this talk we explore
this implication concretely in the large-$\beta_0$ approximation, where the
perturbation series is known to all orders, using a renormalon-free scheme for
the gluon condensate.
