Is Niantic waiting until Saturday and Sunday to increase the number of Power Spots?

I’m only seeing 2 active Power Spots per S14 cell.

For my campfire meetup to be viable, we need 3 Power Spots with a half hour reset at our location or I have to relocate elsewhere.

I’m guessing no one knows at the moment, but I thought I’d check just in case… does any know if “more power spots than usual will be active” applies only to Saturday and Sunday?
