I have made several suggestions, both in these forums and in conversation with several individual stations.
They amount basically to this:-
1. Reduce your gains to a much lower level, yes, you may lose a few distant strokes, but your overall efficiency will be much higher.
2. Increase the thresholds to a good level, this will stop many forms of annoying interference triggering the station, and "local lightning is always going to exceed the threshold anyway.
3. Make use of the station itself as a tool to find your local sources of noise.

taking a look at http://wwlln.net/n showing the thunderstorms active on earth, you may notice that there is a lot of action within reach of the Canary Islands, especially towards the west and south. Attenuation over sea is low, so the sferics can be recorded well here. You should note the the station is also receiving sferics from the Americas and contributing to the location there. In South America and Africa there are simply not enough stations yet so many real signals the station here receives are not yet used by the network.
2.) I have no indication whatsoever of local noise sources. There simple is no "annoying interference" triggering the station, the signals are almost completely from sferics.
3.)There are no local sources of noise of relevance. The only one I have not really managed to trace concerns only the E field, hence the low amplification on this channel.
The bottom line is that I chose to run an "island station" aiming at coverage of the Atlantic around and from the figure below you can see that it works: up to a distance of 1000 km the efficiency is 100%, gradually dropping to 80% at 4000km. Then the American continent comes into play and the recognition rate drops.
You chose to run a station optimized for local recognition and that's what makes the difference.
A quality measure of an island station is the S/N ration, where N means real noise and not sferics from distant strokes, and of course the location accuracy. The efficiency and efficacy measure are of little value here.
Cutty has already proposed to make this distinction between isolated stations and integrated stations.
