When I use the fork for scooping, I use my knife to hold the food in place (blade down on the place) and scoop the food into my fork right side up. Upside down makes abolutely no sense to me. It defies all logic.
As far as cutting, I'm right handed. So I will cut with the knife in my right hand and fork in my left. When the piece is cut I switch the fork to my right hand and eat.
I do not cut multiple pieces when I eat. I cut on piece at a time. Sure, eating may be slow this way, but eating slow is better for your digestive system anyways, and it provides a better opportunity for the meal to be more of a social gathering
