The abstract, in full:

Severe acute respiratory syndrome coronavirus 2 is the causative agent of the ongoing coronavirus disease pandemic. Initial estimates of the early dynamics of the outbreak in Wuhan, China, suggested a doubling time of the number of infected persons of 6–7 days and a basic reproductive number (R0) of 2.2–2.7. We collected extensive individual case reports across China and estimated key epidemiologic parameters, including the incubation period (4.2 days). We then designed 2 mathematical modeling approaches to infer the outbreak dynamics in Wuhan by using high-resolution domestic travel and infection data. Results show that the doubling time early in the epidemic in Wuhan was 2.3–3.3 days. Assuming a serial interval of 6–9 days, we calculated a median R0 value of 5.7 (95% CI 3.8–8.9). We further show that active surveillance, contact tracing, quarantine, and early strong social distancing efforts are needed to stop transmission of the virus.

So...

That's saying the initial R value was 2.2-2.7...

And in the last studied out real of Andes, they said it was 2.1...

Since you're offering to answer questions:

Why shouldn't we compare the initial R values since we know both?

If we have a median R value of something with a best case 40% mortality...

By that point we're already fucked.

Like, I'm starting to doubt facts and/or logic are gonna help you here buddy.

But that was a nice source you didn't understand, so thanks for linking that.

Edit:

Like, it almost feels like you think "r value" is a set number and not a descriptor of how it's actually spreading...

https://en.wikipedia.org/wiki/Basic_reproduction_number

You just don't understand what the words and phrases you keep using mean...

Like, if contact is minimized, it will be lower...

If someone goes the World Cup, it makes the number skyrocket, despite the virus not mutating...

You just fundamentally don't understand any of this buddy, and instead of asking questions to learn, you want a slap fight.

I'm probably going to give up on helping you soon
