Yeah, you really have to throw the data from China out. To include it is knowing you are including false data, which defeats the purpose.
But I have been wondering if maybe the resolved cases don't include all people that tested positive and recovered, especially in regards to other countries. What I mean is maybe people tested positive so they are included in the total cases, and recovered at home or whatever, and resumed their lives but were never 'officially' cleared and declared "recovered". I think the criteria is two consecutive negative tests over a certain period. So if someone didn't take those test they would not have been counted in the "recovered" group, even though they have recovered and are back to their normal lives. We can only hope that is the case.
This is one of the problems when you have different countries collecting data in very different manners. You really need some uniformity.
