I think if you fill in all the gaps then you are seen as having an unbroken record. I hope someone will confirm this.
What I do is to always post my blips chronologically. If I've been away for a fortnight, I will start with the first photograph taken whilst away. I'll probably post two a day to catch up.
Of course I'm still taking photographs daily whilst I'm catching up and they will be added in their turn.
So usually it will take a week to post a fortnights photographs, by that time I'm 7 days behind, and that takes me another 3 days... so altogether it takes me a fortnight to get back up to date again.
All the photos are posted in the order taken, so it's never really a back blip.
I hope this is helpful
