Before revision:  We simulated multiple models currently used to study the COVID-19 pandemic and computed the relation between these two fractions in all those models . Across most models currently used and for most realistic model parameters, the relation between the two fractions is consistently linear and model independent.
After revision:  We show that those two are approximately the same in exponential models and across most models currently used and for most realistic model parameters, the relation between the two fractions is consistently linear and model independent.
