Rt is based on the rate of change, not the absolute value, right? So if testing coverage is constant in time, then doesn’t it drop out?
Of course, it isn’t constant with time, but it is also probably not changing that drastically over short time frames (like the seven days the author uses), so it shouldn’t throw the results off too much.
