It should be strong if the effect is strong. We find strong signal in noisy data in all kinds of contexts. If all the states with masks and social distancing mandates had, on average, 30% less cases per capita than states without, that would be a strong signal even if it's not conclusive given all the other variables involved. I doubt any other variable could be found that would show that much signal. But we haven't see anything like that.
