I got an upgrade on my first AF flight while Gold (preceded by one KL non-full flight), but then I wasn't the only one and the flight was actually full.
I suppose if "time since last upgrade" factors into the algorithm, it might mean that fresh Golds would tend to get their first upgrade fairly soon.
