Hi Marc. Welcome. Those FFAs can drive you up the wall. They can happen when you think they shouldn’t and don’t when you think they should. However this is how you learn about things. You can’t prove or disprove something until you get enough data. Even then it still may not be possible.

The miniPBOs shows the Sumatra quake had an affect on the Bay Area, but what kind of an affect did it have? What kind of an affect did it have on the West Coast if any at all? Take Care…Don in creepy town
