Reverse NILs in CQ WW: 2014; 2005 to 2014

The basic notion of reverse NILs (rNILs; or, I suppose, RNILs) is described here, along with a description of a simple script for calculating rNILs for CQ WW contests and the result of applying that code to the contests for 2005. See also the comments at the end of that post.

Here are the results for 2014:

We can also look at the results for the 10-year period from 2005 to 2014; the only difference in the way that these decadal tables are calculated is that the minimum number of rQSOs is raised from 50 to 250 for tables pertaining to all QSOs and from 25 to 125 for those pertaining to intra-W QSOs (that is, the value of the variable MIN_QSOs is changed from 50 to 250).
