The serial interval is/was three days, that's not the same thing as doubling time. Serial interval is how long it takes someone who just got infected to become infectious and pass it on. Regardless, the answer is no. Inflection points should be clearly visible because the underlying dynamic is organic, and mass-scale human intervention is inorganic/synchronized. Remember - the policy is justified exclusively on the basis of creating those inflection points. Nothing else. If no such points are visible the policy is a failure and we're left with only the downsides (of which there are many!).
