re: If inventory units stayed same from q1 to q2, doesn't this mean that production of completed units in q2 was exactly equal to shipments of completed units in q2 ?

Yes, except some units were written off and not sold. Obviously they were produced.

Therefor wafer starts in q1 (not q2) should be measure of potential perfect-yield capacity.

No. B does not follow from A. Some of the units sold or written off in Q2 were produced from wafer starts in Q4 or even earlier. So the wafer-out capacity, which is what Doug was using to estimate yield should be a mix of Q2, Q1 and earlier capacity levels.

But using a 7 month old slide giving AMD's wafer-out capacity as the basis for yield estimation is pretty funny. And when caught, to compound the error by talking about Q3 and Q4 wafer starts is even more ridiculous.
