Mark,
Thanks for the link. Looks like Fred saved me the trouble of making
those calculations myself.
I entered the data I had already collected and came up with a value
for 7/02 and 1/05 of about 3450 ft-lbs/lb. In comparison, the 6/06
was down around 3000 ft-lbs/lb. Do these numbers make sense with
what others have seen and can these batches really be so much worse
than the good batches of TAN II?
Thanks,
Eric Monda
