I recently read another post that said that the view EASY as an order of events, ie eat, activity, sleep. When I was on a 3 hr EASY I would aim to be within 30 mins or so. That is about a 2.5 -3.5 cycle, using DS needs to guide the timing of things. DS was alwaysa quick feeder. That just meant he had more activity time. I would put him down for a sleep when he showed tired signs. If DS woke early from a sleep eg 45 mins I would try hard to resettle, but if it was over 1 hr 15 mins I would give it a go, but if no success get him up and start the routine again.
HTH.
