This is a component of the ad hoc covid19 data project connected to the FUFF platform (fuff.org)

At the bottom of this page are tabs. they link to the other sheets/pages
important examples on other web pages:        
the danger of averages - (this is also about the effects of clusterization):
http://fuff.org/data/cr2_about_clustering_and_averages.html
the miracle of math(sk)s - (it is valid for other interventions as well):
http://fuff.org/data/cr2_example_masks.html
the risk with protecting risk groups
see tab '4 cluster example'
some other example results for different parameters      
initial model, without the cluster system, no measures
population: 80,000,000 devide: 100 0 depth: 1 days: 15
no measures, majority of population behaves normal
population: 80,000,000 devide: 85 15 depth: 1.15 days: 15
sluggish reaction, early loosening of measures
population: 80,000,000 devide: 67 33 depth: 1.15 days: 15
earlly drastic measures, standard values, less strict after 100 days  // because of clusterization infections increase although average spread is only 1/person -> the dangers of averages example for explanation!
population: 80,000,000 devide: 67 33 depth: 1.15 days: 15
earlly drastic measures, excessive testing and monitoring reduces the number of days infected/person, so that spread/person is half of that what you see in the chart 
population: 80,000,000 devide: 67 33 depth: 1.15 days: 8
however loosening the grip, still leads to... 
population: 80,000,000 devide: 67 33 depth: 1.15 days: 8
initial model, without the cluster system, but with a succession of measures and loosening
population: 80,000,000 devide: 100 0 depth: 1 days: 15
another example of buying time
population: 80,000,000 devide: 75 25 depth: 1.1 days: 15
initial model, without the cluster system, excessive testing and monitoring reduces the number of days infected/person, so that spread/person is half of that what you see in the chart 
population: 80,000,000 devide: 100 0 depth: 1 days: 8
this effect makes me curious: is there a flaw in the model, or does 'herd immunity' work here? I have not had time yet to check this  
                                                   
new: I modified the model so that you have two variable parameters over time for measures: lockdown (reducing the spread prob for each person), and new: excessive testing (reducing the period of days a person spreads before becoming isolated) 
sluggish reaction, early loosening of measures
population: 80,000,000 devide: 67 33 depth: 1.15
here you can see the possible importance of clustering. without clustering the parameters suggest a solution that might be is not there:
population: 80,000,000 devide: 100 0 depth: 1
