I think of ER as sharpening the axe. not sure how many trees I will cut down or when, but with a sharp axe I will cut them down swiftly and with ease. I think of IR as actually getting down to swinging the axe. Both are needed. ER is a good terminal goal because it enables the other goals to happen more freely. Even if you don’t know the other goals, having a sharper axe helps you be prepared to cut the tree when you find it.
ER vs IR. I am not sure what your question is.
