The top set of ratings (that you can change) are the inputs. If you choose the "tactic neutral" button, it will treat these as base/m2m ratings, then convert them to whatever tactics you select. If you don't check that box, it assumes those are the ratings you'll put up with whatever tactic you selected, so it won't convert them (but if you switch from LI to RnG, you would obviously put up different ratings, so you'd need to manually change the ratings to account for this).
