Is "When will Peak Oil occur" the only/best question?

Which is worse? (even if we didn't worry about GW..)

Case A: Oil peaks at 120 mbd in 4 years

Case B: Oil peaks at 90 mbd in 20 years

       (Today ≅ 85 mbd)

Algeria
Peak Year: 2009
Peak Output: 2.09 mb/d
2005 Output: 2.01 mb/d

Google Calculator:

(2.09 / 2.01)^(1 / 4) = 1.00980509
Avg. Growth of 1% per year for 2005-2009

The U.S. Energy Information Admin projection: annual growth rate of about 2% per year during 2003-2030.

So do the "consequences" start in 2009 or in 2005?
