I just summarized the last 41 bore readings I took.  I just used 
inside calipers inserted about 1/4" inside the shank end.  The mean is 
the average for those not statistically inclined: 


Tenor MP Bores	
N	41
Mean	0.6684
StDev	0.0083
Median	0.669
Min	0.648
Max	0.687
Range	0.039
6*StDev	0.050

Thanks Keith, I'd been wondering about that, I've been using .665 for 
the Saxscape pieces, based on the Babbitt/Link pieces I had measured.
