I've stated in this thread and elsewhere, I do anticipate our mortality rates wil come down as more tests are conducted. However, I don't agree that the stats aren't accurate just because it is short term.
Tying it into sports, if you look at an entire season or career for a player, there stats might be different on a longer term basis, but it doesn't mean the shorter time period is false. If I said that Buddy sucked at 3PT shooting his freshman year, that is a true statement as he shot 24%. He did improve throughout his career. But just because he shot 46% as a senior, doesn't make my statement about his freshman year false, it just improves his overall percentage for his career as you average it out.
It's the same way with the virus. The numbers today are accurate. Today. They may change over a longer period of time, but doesn't make the current numbers false and still shows the seriousness of the virus. They may or may not improve dramatically. Improvement may happen, but it is not going to change the base case. Back to the sports analogy, Rashad Odomes might improve in free throws, but he isn't going to be Hollis Price. He might go from 45% to 65%, but he will never be a 91% shooter his senior year. He will still be a less than average shooter.
I also don't buy the line of the assumption I have seen repeatedly that you can't give accurate stats because we have no idea how many people may have this and haven't been tested or go to the doctor, but state the flu statistics are accurate. You think every person that gets flu symptoms goes to the doctor and gets a flu test? They do not.
