" 3.3.3. Swarming behaviour
 As with other behavioural traits (see section 3.3.2.), a 4 point scale is used to classify the swarming behaviour of test colonies (Table 6).
Note that typical supersedure queen cells are not considered as swarm cells.
 All symptoms of swarming behaviour (score 1-4) are noted on each inspection.
At the end of the testing season, the lowest registered score, representing the most extreme expression of swarming behaviour, will be assigned as test result.
All observed (and usually destroyed) queen cells can be counted throughout the season to quantify slight differences between colonies within the same score. Those differences can be expressed be intermediate scores (3.5, 2.5, 1.5)."
