What works best?
24 hours learning in 24 hours or 24 hours learning over 24 days?
By the hour with no intervals or a gap of six days and 23 hours?
I ask as I've sometimes done the 24 hour thing working on a play, a short film (over night shoot), or writing. You stretch it out over a long period and you may water it down. The experience and the learning is less of an event.
