I see...and that makes sense.

I guess that no conclusive and statistically meaningful results have yet emerged...perhaps because lots of times (and data) to achieve a high confidence is needed (?). Or it's in the pipeline ...moving slowly...(?).

Some progress is always good. FFA, though, is attempting to solve the "seconary events" type of problem. Predicting the primary (large) event is still the main "problem"....

Whomever understands the causes of the main event(s) should also have insight into the secondary events as well. Perhaps vice versa may also be true...(?).

My 2cents worth...
