What has been done in the study is to create a computer program that appears to produce effects very similar to the geomagnetic jerks.
It may or may not be the actual mechanism. The computer program produces phenomena that looks, in the program, very similar to what is observed.
The test to see if it is correct is to determine if the jerks can be predicted by using the information from the program.
If they can be predicted, it will be good confirmation that the computer program is reproducing a phenomena close to reality.
