Before revision:   Crucially, the  regimes are well separated by a self-averaging time period which can be minimized by an optimal resetting rate.
After revision:  Notably, in the last regime, the system is self-averaging and thus the sample average will always mimic ergodic behavior establishing a stand alone feature for GBM under resetting. Crucially, the regimes are well separated by a self-averaging time period which can be minimized by an optimal resetting rate.
