Shan,

"Even if he announces it is only 20% success rate"

Roger is not evaluating your predictions. Indeed, he has stated clearly that he is unable to do so. There will be no announcement of any per cent.

He is merely plotting them onto a map, which will show the occurrence of all earthquakes in those areas.

"Roger was not supporting my method"

No one is supporting your method, because you have declined to state what that method is. No one knows what it is, and so no one could possibly support it.

This is not an English problem, your explicit stated intention was to not reveal the details of your method. Vague hints shrouded in haphazard English nothwithstanding.

Thus, I say "it is not worth the effort" to discuss your method.
