My theory on NBPNP is they tried to kick start following NSpnp closing so quickly with so many applicants -by doing the instant ita at sessions such as dubai, it blew them away (and promptly stopped doing it) and been playing catch up every since to the extent that anyone from approx mid august unless priority 1 or french speaking hasnt got an ita and those that do waiting 4months+ are being held along until 2017 quota kicks in.......the little burst in nov/dec was clearing their 2016 allocation.
