While testing may be(is definitely) less, so is Death Rate (a rather more important stat imo!) - even with a significant number more cases deemed 'Serious/Critical'.
A touch of 'nationalism'/Francophobia involved in your post?
Edit: FWIW, key figures for Germany appear more in line with (actually 'better than') France's than UK's. I'm inclined to think population density could well be a factor.
With a younger population you'd expect less fatalities.
You do realise how these models work, don't you? There are assumptions about the relationship between observed cases and actual cases (it is widely agreed observed numbers are an underestimate), transmissibility, how long that trajectory will last, case fatality rate etc etc etc. Put it all in the spreadsheet and Excel throws out a range of numbers. The worst case one gets presented in the Mail as "DR LOCKDOWN CLAIMS 5000 WILL DIE EVERY DAY", when the actual report contains a more nuanced set of scenarios with sensitivity analyses (i.e. which assumption or factor drive the numbers).
Also, he is not trying to "be right". He does not work for Ladbrokes. He is modelling what would happen under certain scenarios, and the intent is to inform where actions can be taken to mitigate some of those.
The key assumptions appear to be:
1. The virulence of omicron compared to delta. They seems to have assumed a worst case that omicron is as virulent as delta. This seems pessimistic but is the pivotal assumption. Worst case is the safest to start from.
2. the R-value for transmissibility. The assumption is that omicron is 5.4 times delta. This is estimated from the doubling time for cases, so seems sound. There are 700 cases a day right now, and with a doubling time of 2 days, we would be at 10000 in 8 days. In terms of implementing public policy, that means doing something right now, if not sooner.
He also said that if the assumption that omicron is not as severe as delta is borne out, "it looks like hospital admissions may only peak at 2,000 to 3,000 a day, then it’s possible that something like plan B – maybe a little bit plan B-plus – might be sufficient, given the government’s overall motivation to do the minimum possible to avoid the NHS being completely overwhelmed,”.
I think this is a reasonable approach to modelling, so long as people read a bit past the Daily Mail headlines.
Edit: The actual report
I'd hope they are using the more current modelling tools of simulation than flipping Excel .
