Had some time to kill this morning and looked more closely at the 'receiver list' table than I would do normally. Importing and sorting it in Excel identified a couple of things that I found odd:
- From the data sampled, there are 212 users reporting more (and in some cases many times more) than 1000 reports per aircraft
- All of those show location as 'unknown'
- A very high proportion are shown as 'anonymous'
- A proportion of these are reporting very low 'aircraft per day' but a high total report count
