all we really know for sure was that there were at least two blocks created between 03/Jan/2009 and 11/Jan/2009.
That's all we know for sure? We don't know that the next blocks were all minutes apart and there was hashing power at the very dawn of the network to maintain something close to 50BTC/10min? And your argument for completely ignoring this is "the timestamps may not be accurate"?
Ignoring??? I'm drawing what I'm saying precisely from there. The dates in my post are from the headline in the genesis block and from the public announcement. We don't actually know which blocks were when, because god knows how things were moved around and restructured while testing or in preparation for release.
