sizing pellets. worth it?

After washing and lubing pellets last week I thought I would see if sizing them would affect accuracy much. So I ran the remainder of a tin of QYS streamlined through a 4.52 sizer (they are supposed to be 4.50) then i divided them into 3 lots, put one lot aside, ran the other 2 lots through a 4.51 sizer, put one lot aside and ran the last lot through a 4.50 sizer and went shooting....
