RE: Efficiency - readbueno - 2017-11-24
Hi All, After I received a certain amount of ridicule and denial in emails, PMs and to a certain extent even in the forums, Egon has confirmed that there was indeed a malfunction on the European server and as of 07.00 this morning it is now working correctly again.
Thanks to all concerned.
Brian.

A claim for yesterday only when there really was very little activity in Europe that I could find on other live lighting sites using other data sources. I looked at, and variations where offered :

Egon has since said there was a server fault, fair enough, but lets not get distracted from trying to sort out better measures for station performance. The underlying reason for zero used signals isn't overly relevant what is relevant is that zero used signals highlighted a weakness in the current proposed "Effciency" measure.
An "allowance" doesn't really work, partly because of the possible negative percentage but also, and probably more importantly, the enviroment of stations varies greatly so a "one size fits all" allowance isn't really practical. Anything that involves averaging a stations sent count would mask the problem that we are trying to eliminate.
Do we need the "Effciency" measure at all? I'm finding the proposed "Effectivity" a pretty good guide as I make small tweaks here. How ever I do look at the "Effciency" as well.

I would like to change the measure for the efficiency of the stations. It may not be appropriate to calculate only one numerical value, but rather to introduce different possibly even competing measures for the efficiency of the systems.
The first value could indicate how many of the transmitted signals are involved in the calculated strikes. The second value would be distance dependent and indicates how many impacts with a certain distance to the own detector the station was involved.
The current combination of these values (thate what we are doing now) seems to be not usefull for adjusting a detektor.
Any ideas for further efficiency measures?

As I said earlier at https://forum.blitzortung.org/showthread.php?tid=2407&pid=16663#pid16663 , it seems to me that the efficiency algorithm has been improved. :-)
