So you are saying they are aiming for this? You see, if the wave was low, and contained the same amount of population as multiple waves, you can see it would have to start out a lot less steeply.
Ours isn't doing that. It's starting out as swiftly as the lockdown models, but then continuing further before lowering the peak. Assuming the same eventual area under the graph, and an identical initial slope, it has to be higher. I'm going to post a picture next of the graphs growing initially at the same rate, but with the UK version plateauing, which is the only other option.
