I was a little confused when I saw that in the most recent year I was listed as having 40 ABT points, when I knew I only had 15 now. So I asked Ken, and he explained that Barry Silliman uses a formula so that only the most recent 5 years is considered.
Thus the last year stretches back until May 2013. In essence this field of influence changes daily to reflect the last 5 years, (60 months), exactly.
Seems brilliant to me! One has to keep producing or fall in the rankings.
