[Taxacom] are journal-ranking algorithms code-compliant?

If Zootaxa publishes 1,000 papers per year, and half of them are cited 
once in the first 2 years, its Impact factor would be 0.5.
1000/2000 (two years of papers are used)

If it published 50 papers per year, and they had an average of 3 
citations each in the first 2 years, it would be 3.0

If they publish 2 papers, and those are each cited 100 times, the impact 
factor would be 50!

"Impact" is the number of citations per published paper, and only 
citations in their list count.

Big is not the issue.
