I think it's possible we're not in disagreement at all, but I'm struggling to express the issue: to me, "recall" is the task that takes all the effort, "understanding" is pretty much instant. Therefore "recall" is the bottleneck between me now and me using the word in a conversation or piece of writing.
But it's possible that we have conflicting ideas of what recall/understanding means.
