As far as I can tell the higher an items quality the more experimentation points you can apply to it. I have yet to find an item taking more than one type of ingredient that lets you put all of your experimentation points in efficiency usually leaving 2 or three left over for durability. Have there been any test done to see what advantage the extra point has over other races. I play a bothan and was wondering if I might need to eliminate some of my less furry competition.
