> If I understand correctly the data in the new file starts around 1-1-1950 and ends near the end of 2013.
The start date sounds correct, but not the end date. The file [average-link-strength-1948-2013.txt]() contains average link strengths starting 729 days after 1-1-1948 and ending 23369 days after 1-1-1948. The end seems to be shortly after the start of 2012.
The reason I wrote "2013" in the file name is that it's computed from data going from 1948 to 2013. The link strengths in the file run over a shorter range of dates since the link strength on a given date is computed from data at times before and after that date.
