Although 55P/Tempel-Tuttle sheds new debris at each perihelion (which indeed 
come at roughly 33 year intervals) the material that can lead to a strong 
shower or meteor storm is usually not associated with the most recent 
shedding of debris, but with material that may have been shed several comet 
revolutions in the past.  The fireball display that was observed last year 
was traced by David Asher and other colleagues to debris that was loosed from 
the comet in 1333 (20 revolutions ago).  Should we be fortunate enough to 
witness a meteor storm this year, much of the material would likely come from 
dust particles that were shed in 1899 (three revolutions ago).
