Comparison of CTI and tMGE in a substrate designed to exhibit non-zero transient kurtosis. Increasing the intercompartmental exchange rate causes a decline in CTI-estimated isotropic kurtosis, which is captured by an increase in the microscopic kurtosis. tMGE shows an exchange-independent, non-zero transient kurtosis and captures the intercompartmental exchange via the exchange rate k.
