Not as much as I'd like, really. The events at the memory championship are geared towards short-term (not short-term memory, but < 1 hours between memory and recall). Additionally, some events occur twice (random cards, for example) back-to-back; you have to compete, then forget that set and build another memory palace with the new deck.

Great to remember groceries, not so good to remember the parameters for that function you created yesterday.
