No...i haven't. I've laid out what would be necessary to consider ending the current SIP while mitigating deaths. That could happen in a month or two months or three months. The WHEN is the critical issue not the WHAT. If we're three months out and are still looking at hundreds of thousands dead versus a crashing economy the calculus is MUCH different than it would be a month from now. We might be ready to accept 250,000 or 500,000 dead in three months while we wouldn't now. This is not a static target.
While this all makes sense, I want to show you where you're not getting my stance. You are starting with a premise that the current SIP is absolutely the correct thing to be doing right now. I disagree, I think the current approach is disorganized, confusing, and inefficient. Worse, I believe it is incredibly risky. I understand why you think the only possible thing we can do is keep going with this approach and re-evaluating periodically. It makes sense. But I disagree.
I disagree primarily because I have more faith that our doctors and scientists can find solutions in a timely manner than I have faith that our society can maintain its sanity under such a high level of stress and uncertainty. Especially given the fact that we don't have leaders who have any idea how to guide us through this. So I start with less concern that a million people will die, and more concern that too much stress and uncertainty, for too long, might cause a near society collapse.
At least you are willing to adjust the goals as the results come in. That's a good thing and, I believe, sets you apart. I would be willing to do the same thing. But my initial approach would not be the current SIP with businesses all shut down. Here are my thoughts.
First, this is a terrible stress on our system, both individuals and institutions. Good people who run small businesses are being destroyed. Working folks are losing jobs. We are captive in our homes. We can't be told this is indefinite. We simply can't. Your approach seems more academic. But I believe it fails to consider human reactions. Things are going to get very ugly soon. Perhaps if a Churchill or FDR were leading us we could make it. But we don't have that going for us.
Second, it's inefficient. This is sort of a "carpet bombing" approach, when surgical strikes would be more efficient. There are specific demographics involved that would allow us to target things with more precision. We can keep hospitals and nursing homes closed to all but patients and staff indefinitely; and that would be a big help. We can put more stringent controls in hot spots like NY, NJ, Louisiana. Colleges can easily remain online for a long period of time. These kinds of measures would make a huge cut to the number of deaths, without exerting nearly the stress on the system that we currently have.
Finally, it is not sustainable. IMO two or three more months and we would have disaster not seen since the Great Depression. Even if you disagree you have to see that six months to a year would be intolerable. And if we have not yet found a vaccine by time we reach our breaking point, then what?
What we need is a more efficient approach that saves nearly as many lives, but which also exerts less stress on the system so those measures can remain in place indefinitely. Target the demographics that give us the greatest returns. Allow businesses to re-open, but with safety measures in place. For instance, a retail operation should require face masks on their employees on the floor, and a Plexiglas barrier between cashiers and customers. There are a ton of things we could do that would allow us to go back to "close" to normal and still save lives.
The problem with my approach is that if things fall within a range of our current expected outcomes, fewer lives would be saved. But with the current approach, which is not sustainable, we risk an economic and societal breakdown. And if that occurs before we have a vaccine, far more people will die.
For those reasons I believe what we are currently doing is far, far more dangerous than what I would advocate.
