It doesn't take 100% control to make a significant impact. Every % you take off of transmission is significant because the relationship between transmission and cases is exponential.

100% is impossible and was not the point I was making. The only things that is import is R is below or equal 1.

The relation between transmission and cases is not exponential as :

1. Cases can't go to infinity

2. R is variable, and actually changes a lot for plenty of reasons
