Ms Moyagh Murdock:

I think Ms Burns's point is that the numbers are so small that if one saw three in one year, two in another year and six in another year, the margin of error is so high in that level of numbers that it would be wrong to call it a trend. One could find that all of them are pre-October 2010 and there are none in the other half of the study period. The numbers are so small that they could all be concentrated in one year. That is the point here.
