Ellanor, thanks for your kind words about GPLDL. We try to minimize the times beetween the release of an updated Plugin or Theme by the Developers and the time it appears on GPLDL. The update process is pretty much manual though and thus causing some delays every now and then. Usually we have the updates online within a couple of days though and it should only be in exceptional cases that it takes longer. Since we usually only send out newsletters once a week this might be why it seems longer. You can check the GPLDL repositories anytime though. We are also planning on developing other ways of notification about updates.
