I just went through the PACER records...F3000 El MURO Day to see how many records have been set.....since everybody has to set a record on this track you can gauge PS4 PACER SALES.

It's around 400 times set ATM

So I wrote around 150 PSN-IDs down from those records to sent them invites to the Pacer AG racing group, only to find that roughly half of those records were set by PS4 owners who are not on PS+, so around hald of all PACER purchasers are playing PACER offline like a old PSone WO.
