Geopathic tomography - experimental testing of geopathic stress detection by human

A geotomography is a geophysical method of imaging subsurface structures using machine.
My favourite geotomography method is the electrical resistivity tomography (ERT).

The geopathic tomography is a method of mapping subsurface geo-anomalies by verified geopathic person.  It is a some kind of DEVICELESS DOWSING.
My research show me that less than 1% of population is capable to be the verified geopathic person. More than 90% of self-called dowsers and biosensitive people are not able to detect geo-anomalies accurately.

I conducted a very simple experiment to check capabilites of self-called "experts for detecting geopathic stress". I brought candidates on the terrain scanned with ERT method and marked with numbers from 1 to 10 as is shown on figure 1. Their task was LOCATING THE STRONGEST GEO-ANOMALY. They had to tell me at which mark they felt the strongest geopathic stress. As you can see on the figure 1, the center of the groundwater anomaly was right below MARK 04. A probability they could guess it by luck was 1 out of 10.
I wanted to eliminate the luck factor, so that we repeated the test on another 5 terrains.

What is the probability that someone guess by luck all 6 geo-anomalies?
The answer is 1:1000000 or 0.0001%.

What is the probability that someone guess by luck 5 out of 6 geo-anomalies?
The answer is 54:1000000 or 0.0054%.

What is the probability that someone guess by luck 4 out of 6 geo-anomalies?
The answer is 1215:1000000 or 0.1215%.

What is the probability that someone guess by luck 3 out of 6 geo-anomalies?
The answer is 14580:1000000 or 1.458%.
 
What is the probability that someone guess by luck 2 out of 6 geo-anomalies?
The answer is 98415:1000000 or 9.8415%.

What is the probability that someone guess by luck 1 out of 6 geo-anomalies?
The answer is 354294:1000000 or 35.4294%.

What is the probability that someone guess by luck 0 out of 6 geo-anomalies?
The answer is 531441:1000000 or 53.1441%.

For geopathic tomography I work only with candidates who "guessed" 6 out of 6  geo-anomalies.

Candidates who "guessed" 4 or 5 out of 6 geo-anomalies are talented with probability of 99.8731%. Because of their potential, I teach them how to improve their skill of detecting geopathic stress.

I don't waste my time on people who guessed 0-3 out of 6 geo-anomalies. They are not talented enough. They can go to your home to detect geopathic stress and to sell you a product for protection. Many dowsers avoid my test. Are you surprised?
