Yeah for sure, R0 is measured, it's not solely dependent on the nature of the virus itself.
Regardless of what it would have been before measures were taken, and what it might currently be, it appears that the model still isn't correct, at least in the state of Texas. Currently it says we should be using something like 2.7K ICU beds for COVID patients, and in reality right now it's more like 1.2K. This SHOULD translate into fewer deaths, 1-2 weeks from now ,than the model is currently predicting.
Sure hope so, that would be some good news indeed.
