Two quick question; First, could a person have filled out the poll more than once? And if so, can that circumstance be identified and the poll adjusted accordingly?
The reasons I ask is that the last time I looked, there were less than 50 respondants which represents maybe 10% of the entire fleet - which in one sense is a low sampling. As well, with only about 50 respondants, a few duplicates could skew things in one direction.
