Hummm ...
I only saw it when it had been three... but you never know, sometimes they do change original calls. I can’t say I’ve seen them do six of those in one place for one day. THAT would be highly unusual.
I was shocked, too.
The listing at the time was at least 7 or so of the 9 one after the other in the list. Several were 7.0 and the rest above 7.0
And I forget what the one in the South China sea was but it too was 7.0 or above.
