I just read the email from the MEC and they say the red arrows this far out have no meaning -

from the email: “down arrow” days... are posted on the bidding software before the reserve coverage is uploaded in the system. This provides a false indication of “low coverage days” and is sending an incorrect message to the pilots when they see this...

So I'm going back to edit the original post.. but figured most of 'ya wouldn't notice an edit that far back. So there ya go!
