How to compare settling times of DACs

I am unsure how to compare the settling times of the AD5544 and the AD5686, due to the different way in which they were measured.

The AD5544 goes from 0 to full scale then back to zero and has a settling time of 0.9us to plus/minus 0.1% full scale. The AD5686 goes from 1/4 to 3/4 scale settling to within plus/minus 2 LSB within 5us. How do I compare the settling times of these two DACs?
