"Aircrafts reported" uniqueness

In “My ADS-B” page, the panel titled “Aircrafts Reported (All)” seems to be adding the summed numbers together instead of counting total of unique aircrafts reported.

Yes, that is correct. Uniqueness is across a single time bucket + site.

To me, unique count for all sites of the account is more informative, if it is not too difficult.

You’d need to compute that yourself locally, we don’t compute that.

(it would require persistently storing the set of unique aircraft per site per bucket for all sites; this is an expensive thing to do; many things that appear to be simple for a small number of sites turn out to be harder with 30k sites)
