The model was garbage.
When a model misses by a massive 25 times what they predicted only weeks ago, (like the Imperial College model that the crazy media have been using) that model needs to be thrown in the trash heap.
BS.
You can criticize the choice of inputs/parmeters. Criticizing the model itself will have to wait.
Smoking - I don’t think you understand models. A model may be great, but if the inputs/parameters are garbage, the results will be garbage even if the model is perfection. Models and inputs are two completely separate things.
