<< normal air pressure is
 about 15 lbs/ sq in.  So should I infer that it blows its top when the
 pressure inside is 13 lbs/ sq in greater than the outside air pressure of
 15 lbs/ sq in for a total of 28?  Is this the standard for pressure
 cooking?

Yes, it is in addition to (that is to say greater than normal air pressure. I
bought mine at a yard sale for $5.00 because the lady was "afraid" of it. The
safety valve on mine is the lowest setting you can purchase. I do not know if
it is a standard safety valve for the canning process. I bought it because I
wanted tto be "safe" rather" than sorry.
