I agree that if P≥50% then pooling is likely useless. We eventually want to be doing things like testing everyone who has come anywhere close to a known case, and/or testing absolutely everyone who has a fever, things like that. So if we do things right, we’re eventually hoping to be at P<5%, or maybe even P<<1% in the longer term. South Korea is commendably aggressive in testing, and they’re at P<5%, or something like that.
Thanks! Interesting thoughts.
