In my opinion, it is all about linking the security processes. If incident management, risk management and implementing measures are not linked, the reaction becomes slow and then the result will be the mentioned 19days. If the root cause is a human risk, then awareness measures should follow immediately if the risk evaluation is high or very high for the organisation.
The key point is how urgent and concrete the risk is. For an high and immediate risk, 19 days is far too long. For a more abstract or long‑term risk, 19 days sounds "fair".
For me the reaction time needs to defined and evaluted by the inherent risk (incl. the orginal threat)
