It does to me too at first look, but then again... We're only 
seeing about the first 0.4 seconds of the envelope. Listening 
to phasing effects while tuning, that's the eowww sound that 
pulls together about a second into it. Where's the video of 
two seconds into the envelope, for comparison? The agraffe 
shot shows the phase transfer between the left string and the 
two right strings, which seem to be pretty close to in sync. 
But look at the same time frame at the dampers. All three 
strings are moving at different rates! But you can still see 
the traveling wave impulse in both videos. I want to see the 
one second, and two second videos, to see what is happening 
after the impulse calms down some and the phasing effects pull 
in. I want to see the pattern with an obvious false beat in 
the unison, and I want to see the string excursion directions 
in both standard bridge pinning and the Wapin some seconds 
into the envelope, to see if there's a fundamental difference. 
These were the requests I made when I signed up for one of the 
CDs. Speaking of which, was anyone in PTG ever informed that 
it was on them to produce these? That wasn't my impression at 
the time.
