Numerous reports on astronomy websites and even mainstream media
have  claimed in recent days that the number of Taurids seen this
year is higher  than "usual". While www.imo.net has ZHR profiles
for both Taurid streams and  all the individual observers' reports,
I haven't seen an "obvious" graphical  representation of the
average brightness distribution, esp. compared to other  years.
Or an analysis concluding by how much the distribution is  different.
Thus the level of confirmation of the "swarm year" hypothesis  is
not clear to me.

I don't think the enhancement is necessarily in the ZHR  numbers . . . rather 
the fact that
this is a "swarm year" suggests that there would be a  greater preponderance 
of 
brighter Taurids and fireball meteors making up the  normal 5-15/hr. for the 
two streams (Northern and Southern).  In a  non-swarm year, the rates would
still be in the 5-15 range, but with fewer bright  meteors.  That's at least 
how 
I have interpreted it.
