Map Packs?

So if you release a map pack of say 4 maps, does that count as a single map or four individual maps?
Because I have six that I want to (re)release around the same time as a series but the rules say only three maps a week.
But if I released all six as a single pack, Would that be an infraction against the rules?
The maps are: The Floor, Devil's Den, Hell's Reigns, Debacle, Vendetta, and Centerpiece, in case you were wondering.

 

Well that's my plan as of now.
Idealy, I'd like to release them all at once.
Like a campaign.
