Reverse NILs in CQ WW: 2016; 2007 to 2016

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.

We can also look at the results for periods of ten years at a time; 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.)

Here, without further comment, are the results for 2016 and for the period from 2007 to 2016:

We've done enough of these now that I don't think I need to suggest which logs might have rewarded a closer look. And I emphasise that, for all I know, the CQ WW Contest Committee did indeed look in detail at some of the anomalous logs and found nothing amiss. One certainly hopes that this is the case.

Arguably no major anomalies there, although, depending on the resources available to the CQ WW Contest Committee, a closer inspection of some of the logs placed highly in the fourth and eighth tables might have been warranted (maybe such inspection took place; I have no way of knowing).

KV0Q's CW (single-band) log stands out as being anomalous. I have seen no evidence that he was invited to provide an explanation for its lack of recorded W QSOs.

Reverse NILs in CQ WW: 2008

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 2008:

By now the pattern is obvious: if the first one or two entries in the fourth column of the fourth or eighth table are noticeably higher than the values on lower rows, it might have been a good idea for the CQ WW Contest Committee to have examined the relevant logs to make sure that everything was in order and that there was no unsportsmanlike conduct taking place in the form of logs missing QSOs that had in fact taken place, and therefore penalising other stations by causing them to record NILs.

The first few entries in the second and sixth tables should probably also have been examined, to try to understand why the values in the fourth column were so high -- almost always these seem to be due to obvious logging errors, though.
