I can't seem to lay my hands on a precise definition of what that

Better ask the customer. (Even if they are not correct in their
definition, it is their definition that you need to know.)

I guess a safe bet would be to get hold of the competitor's part, measure it
under the conditions that the customer will be using, and make sure yours
will be better. You could also see if the competitor puts a measurement
setup in their data sheet. It gets more difficult if the customer is just
selling the chips and doesn't know how they are going to be used, or what
is important about their behaviour.
