Right, but that requires familiarity with both vintages. If someone were to pipe up with familiarity with both vintages, that would overrule my advice. My advice is merely of the "in lieu of actual knowledge" variety. It's like those test questions:
10.
a.
b.
c.
d.
The answer (at the time I was told) is b., because b. is the most common answer in a multiple choice type test. If there was an actual question, with actual answers, and you knew the answer, that would of course over-ride the b. rule.
