Edit: Sorry, I made a mistake. Trying to measure Rt seems to be a good idea. However it's not clear how the proposal calculates Rt. No formulas and no references to raw data. So I am afraid this is not very useful. This said, I could imagine that an approach which takes the number of confirmed cases and the total number of tests could work to estimate Rt. The idea is that while the number of cases is not a good estimator we can try to get a better estimator using the number of tests as well. It's a bit tricky, however, because a low number of tests could mean that only the probable cases are tested which skews the numbers.
