Yes I remember that slide.
I think I recall a post on this site that there were something like, I don't know, 10? 20? new Kingdom Halls constructed in the USA in 2016.
You don't pull those numbers out of a hat. They had spent years, probably many years, producing this "master plan" (I also recall they used that phrase repeatedly in their presentation).
I also recall elders being commanded to "talk this up" - be positive & proactive, build enthusiasm among the "friends", mention all this building frequently in prayers, etc.
And almost as soon as the travelling dudes got home from showing all this stuff, it all dried up.
