If the Fed bet the NGDP target, quarterly

I have never gotten a clear answer on how target became a verb. What actions would the Fed take to meet an NGDP target.  So lt's make the NGDP betting site.  

What happens in a downturn?  The Fed keeps betting the same NGDP growth number.  But the NGDP target is met by a combination of new credit and Fed losses on the betting site.  So, the downturn happens, assets sold and cash received is all placed on the NGDP target number.  The current  most likely bet reflects the amount of money bet by the Fed.  Hence,  the investors and public will simply algorithmically collect the Fed losses as it restores a dropping NGDP.  You end up with direct payments from the printing press to individuals.
