A lot of the reduction happened under level 3,
What reduction? The whole country moved to level 3 on October 6th with numbers on the rise. On the 6th we reported 424 new cases, there was no day during the level 3 restrictions that posted lower numbers. Over the next three weeks of level 3, daily numbers trebled.
I just think nphet need to be realistic about what is achievable given what's happening in Europe and that many people will travel home on holidays over Christmas anyways.
You haven't said how it would be possible to achieve 150-300 cases per day with reduced restrictions.
