Thanks, Chris.
It just seemed like every report I read after the 8/11-12 peak, suggested
the actual peak was 8/12-13. And the numbers I witnessed weren't as big as some
reports.
Even Spaceweather.com showed this title:
PERSEID RECAP: Who knew the Perseids would be so good? The shower peaked on
August 13th with as many as 135 meteors per hour, making it one of the best
shows in years: _data_ (http://www.imo.net/live/perseids2008/) .

While the brightest fireballs I recorded were on 8/13, the fireball rate
wasn't substantially different between the two nights: on 8/12 I recorded
152 meteors, of which 23 were brighter than mag -4 (15%); on 8/13 I recorded
117 meteors, of which 12 were brighter than mag -4 (10%).
While solidly locating the peak of such a broad shower is tricky, I'd say my
data puts it within an hour or two of the predicted time. My 8/12 data seems
to show more structure in the frequency: the rate rose and fell with about a
30-minute cycle. On 8/13, the rate was much more uniform.
