i take an extra bottom board out with me and put the top super on it with the entrance at a 90 degree angle to the position of the hive. then i do a full inspection of the bottom super. once that is done i put the second super on the hive and inspect that. i switch the supers if the brood chamber has been moved to the top super, it helps releive congestion and reduces the likelyhood the queen will lay in the honey supers if you do not use a queen excluder.
