The goal is to burn as much powder inside the barrel and limit the amount you blow out, on the ground. With the 3F, you are doing just that as you are getting more effective burning. I'm also assuming you stuck with BP before and after. Also, we know that consistency is the game and I don't tap to level. I just pour into a calibrated measure, top off and load. Tapping and refilling will always give you more powder than not tapping. .....
