Has anyone noticed really fast acceptance?

I posted something like 20 articles last night and they were accepted by this morning. I'm posting more now in hopes that this keeps up. I already sold one.

Most articles I submit are accepted within an hour or two, sometimes within 5 minutes. It seems to be quickest if I'm writing for a pool/private request, and especially if the deadline is approaching. I suspect the editors prioritise according to urgency.
