Absolutely nothing
I stay in the lounge as long as possible as the food and drink are very nice. We now go a little earlier as we now plan to answer the security questions at the gate since this is better than the little room or transfer desk - last time it added about 30 seconds to our time at the gate.
But some folks here seemed to want to know the gate early, and you can known the good with high reliability like 6 hours in advance, so I just figured I'd point out the technique.
Cheers.
Excellent answer, thanks.
