Pandemic Severity Index.

I wonder if the reason why CIDRAP's pandemic severity index never took hold is because their percentages don't make sense.   They did not place the decimal in the correct place which makes it confusing.  Plus, Category 1 flat out doesn't make sense because there is not a bottom CFR number used to create a range, which means any flu season qualifies as a category 1. 

The current pandemic severity index levels are: 

Category 1, CFR of less than 0.1% 
Category 2, CFR 0.1% to 0.5% 
Category 3, CFR 0.5% to 1% 
Category 4, CFR 1% to 2% 
Category 5, CFR 2% or higher

Here is the correct way to use the decimal when defining the CFR percent:  

Cat 1    CFR less than .001%
Cat 2   .001%    to        .005%
Cat 3.  .005%    to        .01%
Cat 4.  .01%      to        .02% 
Cat 5   .02%      to        and Higher
