Hi Guillermo,
Yes , Right I got the same issue as well.
Probably you will have to do something like this to overcome the contact date limitation on the recurring delivery.

So the contact date will always be populated using the current timestamp.
I tested using this setup and got the pressure rules applied in the logs :
04/30/2018 9:32:23 PM Loading typology rules (step: javascript/postTarget)...
04/30/2018 9:32:23 PM Applying arbitration 'Test pressure' (threshold reached) : 0 recipients(s) excluded in 0.0s.
04/30/2018 9:32:23 PM Duplicate address in delivery action. : 0 recipients(s) excluded in 0.0s.
