Efficiency

[allsorts]

I would like to change the measure for the efficiency of the stations.

I quite like Cutty's:

Efficiency = Strokes Detected / Signals Sent 
Effectivity = Strokes Detected / Signals Sent - Strokes Detected

Being based purely on the numbers from a given station it removes the influence of the total region count which generally has the affect of pushing a station that sends few but high quality signals down the list.

Not sure how to combine those with a distance. "signals sent" doesn't have any distance information but does that matter? I don't think it does.

Actually, it does... in a 'thought experiment'...

Hmm, whilst I agree that a stations enviroment and location affect the settings (threshold/gain etc) of that station my gut feeling about the above formula is that distance "cancels out".

ARGH! I hate web based editors that drop your carefully crafted message in the bit bucket if you accidentaly load another page in the same tab/window. I'd typed in a load of thought experiment showing that distance doesn't come into the formulas. It also showed that gain governed range and that threshold is best set after the gain/range value to the point where local noise only rarely triggers a signal. Note this was a thought experiment in a nice friendly world not the hostile, real, one. Finding a setting for the threshold with variable local noise levels might be tricky.

The range a station is optimised for is a choice for the operator but for most benefit to the network ought to follow that relatively isolated stations go for range and ones with nearby neighbours restrict their range.
